Werecently purchased the TireTrackersystem at a Rally in Indiana. It is a different system compared to one picturedin the link. We haven't installed it yet but plan to do so in the very nearfuture, It was an expensive purchase but something we just felt we couldn'tlive without any longer. It has some features we liked including a notificationwhen tire temp suddenly changes, alerting the driver to a potential problem.Jeff from RV safety came across as knowledgeable and credible at the variousrally presentations he made on safety. I would not be without one. Ihave been happy with my PressurePro TPMS. It has been on for 9 years now. I bought itbefore I took delivery of my '08, and have had the sensors, withnon-replaceable batteries, in place since then. Around year 2, I had a sensor go bad. It was replaced, no cost, under warranty. At 7 years, in very cold weather, I had asensor (1 of 10) that would be slow to register, and would occasionally loseits connection to the monitor. So, with7 years on the sensors and an expected life of 5 years, I replaced all thesensors. I am at 9 years on the system,with no other issues. As Larry saidabout his system, programming the sensors is annoying but other than needing topress the buttons just right, is not onerous, particularly since I have onlyneeded to do it a few times in 9 years.
I should note that I set my tire pressure with adigital pressure gauge. That gaugeagrees with the two analog gauges on my compressor, e.g., I can set them at 80psi, let the compressor charge the tire, then check the tire and I read 80psi. However, the reading reported bythe sensors can vary by several pounds. That really doesn't matter, because the sensors are intended to measureand report a CHANGE in tire pressure. They do a good job of that, and as the programming is individual sensorrather than group programming, if a number reading is off by a few pounds, thatis of no consequence. A loss of pressureon one sensor will be reported as quickly as a loss of pressure on another andis a function of percentage pressure change. There is an old expression - "Man with one watch knows the time. Man with two watches never sure." As the sensors are highly reliable indetecting and reporting pressure changes, but not as much in reporting actualpressure, I do not use them to set my tire pressure. I make the tirepressure right and use the tire pressure to set the sensor.
My TPMS, PressurePro, does not require a pre-departure scan. Once I turn it on, it takes a few minutesbefore every sensor "logs in" to the monitor. Once they do log in, any low values set offan alarm. Pressures are subsequentlychecked by the sensors every few seconds. If a pressure falls outside of the range, an alarm is immediately sentto the monitor. If all is ok, each sendspressure information to the monitor every few minutes. It is no distraction unless an alarm goesoff, but that is something I would want to know.
In 9 years of full timing, I have gotten one alarm from a failed sensor, and Ihave seen a number of first things AM alarms where a tire pressure is down afew pounds, due to the cold weather overnight. The pressure in the low tire is displayed, allowing me to decide if Ineed to pull out my compressor, or if it is OK to roll. Case in point, currently my TOAD pressuresare reading 29 to 30 in the morning, and I usually take them up to 33. So, the alarm goes off, I look at thereadings, and I silence the alarm. It willrepeat in a few minutes if the pressure stays low, but usually, a mile ofdriving brings the pressure up to my "OK" range.
When you check the pressure in the morning before starting out, you travel,knowing ONLY what the pressure USED to be. With a TPMS, you know what thepressure is, all the time. For some, they see no need for a TPMS. Iwould not travel without one.

TST (Truck System Technologies). We have used this system for a number of years on two RV's.Works just fine. I change the batteries each Spring simply to avoid having tochange them on the road should they fail. Much easier to do at home at myconvenience with all the tools I might need.

"How much space does the read out gizmo take on thedashboard? He has a Scan Gauge up there now."
Can't speak to all brands, of course, but thegeneral answer to your question is 'not much'. Perhaps an area say 3' long by1" deep. And it doesn't have to be right in front of the driver's eyeseither, especially if there is a passenger to keep an eye on it now and then. Ihave a Scan Gauge, GPS and a TPMS and they all get together just fine.
"Canthe sensors be put on if one has the air-thru filler valves, or do thesesensors replace the filler valves?"
The sensors replace the valve stem cap.
"Limitedphysical acuity will probably preclude self-installation, unless it is reallyeasy to do. What sort of dealer (tire?) should we contact, ifneeded?"
As long as a person in your group can checkthe tire pressure now, they can install any of the TPMS systems. You justremove the existing cap and screw these in their place. However, sometimes, depending on the type of decorative wheelcovers you have, the length of the valve stem and the size of the sensor, itmay be necessary to enlarge the hole on the cover to accommodate the sensor. Ihad to do this to the two front wheel covers on my 2015. The holes simply werenot large enough. Now I could have added a short extension to the valve stem toget it further out, but I really didn't want too. A drill with an abrasiveattachment made quick work of making the hole larger. Plus I'm guessing thatsome of the metal I ground off would help offset the additional weight of thesensor.
The first set of sensors we had did not have the flow-through stemfeature. Before every trip, I like to get the tire pressures balancedbecause tires simply lose air over time. With the old system, I had to take allthe sensors off to do this. Doable, buta PITA. The ones I have now have the flow-through stem so, before each trip, I justcheck the tire pressure with my gauge and use my pump to get everything just asI want it. A very convenient, time-saving feature.
I had the experience yesterday of having a tire blow out on my Lazy Daze26.5. It was the left outer tire that blew as I hit something on the waysouth on I95. I saw it and had tried to avoid it but no luck. My TireTraker system did exactly what itwas supposed to. It started flashing a bright red light and beepingloudly warning me that I was losing pressure very quickly. I have ahearing loss and I was still able to hear it quite clearly. I droveslowly to the next exit and had the spare put on the camper. While thespare was being installed (for $25) we got to witness the Eclipse within sixmiles of the center of the path.
Fortunately, I had ordered a TireTrakersystem last week and had it installed the night before I had the tireproblem. This is the first trip I have made with the TPMS and I am sureglad I had it. Being able to check on what pressure was in which tire andsee the individual temperatures is very helpful. I am now a believer inTPMS systems and their value to RVers. Had I not known what happened Iwould have had to pull off to inspect the damage and the traffic was VERY heavygoing south on I95 in South Carolina at the time. Stopping on the highwaywould have been a very dangerous option but I did not have to thanks to theTireTraker system.
I bought a TireTraker because I hadheard about it from some close RVer friends who have had one for manyyears. In the latest issue of an RVmagazine, they reviewed all of the popular systems including the one Ibought. It was very easy to install asthe manual was quite complete and easy to follow. One of the reasons I bought this system isthat the individual sending units attach directly to the end of the tire valvestem and weigh less than 1/2 an ounce. Ican add sending units when pulling a trailer. No having to remove a tire from rims or anything like other TPMSequipment I have seen. The batteries arecheap and plentiful and can be changed without removing the sending units. It is a well thought out system and I am sureglad I had put it on when I did.
When I purchased my system I was told by the representative of TireTraker that I would need their"Repeater transmitter" as our RV's have an aluminum skin. Thatmay be true with a trailer but the basic system worked just fine on my 26.5 LDand the signal strength was fine in my vehicle.
This little device made a potentially bad experience into a manageableone. It kept me from having to stop on a crazy busy road and risking anaccident. It protected my family and my dear little Lazy Daze RV. Thatmade it worth every penny it cost, to me.
I hope you never experience a blow out at speed as it gets exciting fast. Having safety equipment like the TireTrakermakes my confidence level go up a notch while cruising along at 70 mph on abusy highway.
I really liked how simple the TireTraker was to install. Iinstalled the batteries on the sensors and screwed them on in place of the capson the tire valve stems. Next, Iprogrammed the controller by identifying each sensor, it took less than twominutes to finalize the programming on the system. I spent less than 10 minutes installing theentire system (including the repeater) myself and getting it setup.
My system uses a battery inside the receiver which will last for a month ofeveryday use they tell me. The kitincludes a charging adaptor that uses the cigarette lighter or you can use aUSB port to charge it up. The receiveris smaller than my iPhone 6. Onenegative on the TireTraker is that you cannot leave the system plugged incontinuously, the instructions tell you to charge it regularly but don't leaveit plugged in 24/7. The battery can be overcharged and damaged if leftcharging continuously.
The kit has a dashboard mount but I used a piece of Velcro to hold it inplace. In the kit are included a set of locks to secure the sensors fromthieves if you feel it is warranted.
Overall I have been very impressed with the quality of the TireTraker kit and it works great! I have looked at severalof the competitors and they all seem to be very nice as there are several waysto get the same information.I am handicapped and don't bend very well as Icrushed five discs in my lower back. Even with my limitations, it was very easy to install and setup.
Having a serious hearing loss I had to find a device that would get myimmediate attention in times of emergency. The receiver has alittle red lite that flashes very brightly as well as a loud beeper. Whenit went off I was immediately aware even with my limitations.
Safety equipment is a "must have", and since I do most of themaintenance on my vehicle it had to be simple to maintain as well for me to buyone. There are some nice systems out there and I came close to buying asystem with the blow through sensors but decided against it as it would requireshorter valve extensions or having pressure pushing on the extension mounts. I really did not want to have to remove wheels to install parts. Thesystem I have made it as easy as checking the pressure, just change the capsand the installation was practically done. The programming was easierthan putting the sensor caps on.
I am happy with my purchase and feel it was the best option for me. Ihope that you folks that are in the market for a TPMS have an experience likemine has been. Life should be so simple all the time. Good luck andsafe travels.
Like you, I too havethe TST 507 flow thru...I just thisyear replaced the batteries, even tho they were still working fine..justthought that nearly three years of use might be pushing it, and wanted to dothe replacements before needed, at my leisure...grin.
I'm very happy with the system--and love thetemp as well as pressure readings. Keeps me informed what temps are runningespecially when driving in the south west in 110 plus weather.
I just had a "loss of air" on theinfamous inside passenger tire..the alarm told me instantly there was anissue..got me stopped asap.
The system has paid for itself several timesover.
Our Doran RV360 is still working fine afterfive years.
I wouldn't want to travel without it working.
I have the RV 360 as well. This trip west is had trouble with two sensorsintermittently losing contact with the receiver. I called the company and they confirmed mybelief the batteries are getting weak. The sensor life can be prolonged by (being more diligent than I) takingthe sensors off when the RV is not in use. I've had the system for 4-5years. I purchased extra sensors for the Subaru. I need to get metalstems for the car before adding the cars to the system.
More recentdiscussion/reviews on TPMS at:
Your input for an Easy UseTire Pressure/Temp Sensor System - iRV2 Forums
Do you use arepeater with your setup, Ed?
No. Not on our'08 MB and not on the TK. Never had a reception problem so far.
But I only have the sensors on the camper, noton the Jeep. The wheel style on my Jeep doesn't have holes large enough for thesensor without me adding an extension to each tire, which I rather not do.
I just keep the rear view camera on whiledriving and watch for black smoke which might indicate a flat tire on the Jeep.
We have the EEZ TPMS and tow a Subaru. Themonitor picks all 10 sensors within a few minutes and we've not lost aconnection once it's turned on. In other words, does not need arepeater. This system gives us PSI and temperature readings for each tirewith the capacity to change settings. I'm liking this.
If one gets the typeof TPMS that plugs into a cigarette-lighter-style 12V outlet, the onlyinstallation that might be required are all metal valve stems and toad. The monitor for the TPMS can just sit in a drink holder or some other pocketthat can be reached by the cord. They alarm if there is an issue, so youdon't need to have the monitor "front and center" to watch forproblems.
For the dualies on the coach, you'll want to getthe stems from someplace like Borg or Tireman, for the toad we used DiscountTire. You do not want to attach the weight of the TPMS sensors to the endof a rubber stem or flexible extender; you want solid metal valve stems (and inthe case of the inner rear duallies, you want the stems supported by astabilizer as they stick through the outer dual rims).
We generally advise against Camping Worldtouching anything on a coach (although there is a handful of CWs that we haveheard aren't bad. That hasn't been ourexperience).
In response to Chip,the TPMS I purchased and am trying to decide whether to keep or return is a TireMinder Smart TPMS that uses one'sphone for displaying tire data and alerts. It's a fairly new model.
The valve cap pressure sensors communicate witha TireMinder module that can beplaced anywhere in the cab and which then communicates with one's phone viaBluetooth. Assuming it works, I like this approach because it means one lessscreen in the cab.
Also, the TireMindermodule alone will signal an alarm with just a tone and a light. You thus cancheck the data on your phone only when needed, not having it as a constantpresence, and distraction. This is much like how factory installed TPMS workson most cars.
Our LD is a 2003 26.5' Rear Bath and we tow aJeep Wrangler.
I use the TireMinder system. Havingworked as a Test Engineer in a past life I have a bit of understanding of labvs real world situations. I will not nor am I able to defend any companybut having said that most folks don't read the spec sheets or have expectationsof equipment that the company will never meet. Glen (colddog)
For instance, I did not install the wirelessbooster so I expect that I will lose signal from the transmitters. Also, there will be interference fromassorted other wireless transmitters that a boosterless system will not be ableto overcome. Having read the spec sheet I understand the system isaccurate to plus or minus 3%. In the real world on my standard tirepressure of 75, it can read anywhere from 72 to 78 and still be within therange of 'normal'. When you toss in thetire gauge itself you could have an error of another 2 to 5%. If the'errors' go in the 'wrong' direction you could have an error of 8% or more -meaning tire reading with your tire gauge could be plus or minus of 6 pds on mystandard 75 tire pressure ie 69 to 81.
So the question is should I buy a TPMS. Frankly, I use my system because I'mlazy. I will know when a tire goesflat - I'm very sure of that. I use thesystem to 'check' the air pressure before I drive off. Yes, there is a cheaper way, like goingaround with a tire pressure gauge but like I said I'm lazy. This ensures in my personal life I'check'. My recommendation -- Ifyou don't have an extra 300 to 400 dollars and you ALWAYS check tire pressures before you drive off tosave your money.
Other than therecent blowout, we have had a couple slow leaks. I'm more concerned about our toad's tires, there is noway of knowing what is going other than the view from the camera. worthwhile.
I know several LD owners who had flats on theirtoads and never knew about it until they could see smoke or passing motorist flaggedthem down.
One toad burned to the ground. Preventing thisalone made the purchase
One thing I love about the TPMS is NOT having todaily manually check the tire pressure, It takes about ten seconds to scrollthrough the ten tires, on the TPMS's monitor. It a real pleasure to use on acold, rainy morning.
Not having to manually check the pressureprevent any air from being lost, during the checking, which can add up on along trip and require adding air. I rarely add air while on the road.
I would not want a system that uses my cellphone as it's monitor, preferring it to be completely stand-alone, so nothingneeds to be done other than turning on the ignition. Make it as easy onyourself as possible is my logic. YMMV
Our TPMS-TireMinder TM66 hasa wireless Signal Booster. Prior to setting up the booster when I originallyinstalled the system, I got several "warnings" of both air pressureand temperature failures.
Since activating the booster, I have had nofalse warnings and one warning of a lost signal from a sensor (batteryfailure).
If the rig has been sitting in the driveway fora couple of weeks or more, I will check each tire manually. I use an analogtire pressure gauge manufactured for TireMinderwhich is stated to be within +/- 1 psi accuracy. The TM66 itself is stated tobe within +/- 2.7 psi. This would suggest that there could be a variance of +/-4.7psi. Is it perfectly accurate? Probably as good as others, I suppose. I haveno issues with the system other than those I have mentioned.
While traveling, I rely on the TM66 monitor todetermine air pressure before hitting the road.
ONE THING: TireMinderstates that a Scan of the Sensors be taken prior to departure. The manufacturerstates that if the rig has been stationary for more than 9 hours a scan isneeded to update the accuracy of the TPMS. It's a simple matter of pressing twobuttons on the monitor and waiting about 20 minutes before departure. Then Icheck each tires pressure/temp via the monitor. Easily done and part of mytravel routine.
I am not certain if other TPMS's need apre-departure scan but it would seem to be a prudent action to take. If fornothing else, a little peace of mind.
We started using a TPMS (Pressure Pro) in 2011. We had asituation earlier where we discovered low pressure in a toad tire that turnedout to be a nail, and if we hadn't noticed the low-ish looking tire, we likelywould have done damage. That tire neededrepair, and a TPMS would have shown that slow leak.
Our initial experience with PressureProwas frustrating. One seal kept causing a tire to leak down. We gotnew seals. Another sensor failed bizarrely reading very HIGH pressures(in a construction zone. In a torrential downpour). The sensorcontinued to send odd readings even when removed from the wheel. Tap iton the counter and the reading would change. Pressure Pro had never heardof such a thing.
After replacing that sensor (and the seals in all the others), the system hasbeen solid. It actually alerted us to yet another nail in a toadtire. We replaced all sensors in 2016 since a couple started failing(internal batteries).
At a minimum, we would always have a TPMS for a toad. We also like having it for the coach. Now, you do need to make sure you haveone-piece metal valve stems on any wheel that has a TPMS sensor, and supportany long stems with a proper stabilizing grommet (e.g. if you get Borg stemsfor the rear duals and they stick out through the holes in the outer duals).
Our research showed non-replaceable battery sensors were a little lighter thanthose with replaceable batteries, so that's how we chose our TPMS. Lessstress on the valve stems. When the current sensors start to fail we'llrevisit the TPMS options at that time.
N.B. - Valterra has purchased Minder Research, the makers of TireMinder.
I don't understandwhy you would remove them for manual air checks? That is one of the mainpurposes for having them. In the case of the LD, we use flow-through sensors andthey are never removed except to replace batteries. On the Subaru, we use thenon-flow through so they are removed when we have to air up the tires. While weshould remove sensors when parked for any extended time to preserve the batterywe never remove them. So, for over 9 years now we have had TPMS on our LD.
On our previous model the Doran RV 360 we had battery failures which required the sensors bereplaced. On the EEZ RV model, wehave used since Jan 2014 we have had one sensor fail to work properly that wasreplaced under warranty and other than that no air loss because of a sensor.
The only alarms we have had are the occasionalbeep if the monitor temporarily loses a sensor. That is partly my fault becauseI don't have a regular schedule for replacing batteries. Recently, I set up therepeater to see if that completely eliminates that from happening but have onlyused it once so can't comment on that.
For me, TPMS is just another form of insuranceand convenience. In my case, I hated checking air pressures every time weheaded out.
All that said, I agree, that they aren't perfectbut it works for us.
Our Doran RV360 TPSM is almost five yearsold, with two of the sensors replaced due to failure. It has worked, without failing,since new and has stayed accurate
A repeater was added early on after losingcontact, at times, with the inside dual tires.
The biggest problems have been the difficulty ofprogramming and the limited pressure differential range. The Jeep's oversize tires often alarm low, on coldmornings, and can have a high-pressure alarm the same day, if driving on a hotday.
I have compared the Doran's accuracy to several digital pressure gauges and the sensorsare within a pound or two of being the same. The Doran updates veryquickly, even after being off overnight or days, useful for when adding air,which isn't very often. Not losing airevery day, while testing, and tight Michelin tires, let us go for weeks orlonger without adding air. In fifteenyears, I have never used our 12-volt compressor, on the road, ordinarily airingup at home. I should plug it in some timeto see if it still works :-)
The Doran'sbiggest fault is the non-replaceable batteries. On the plus side, 8 of the 10sensors are still good after five years. Iknow folks, with TPMSs, that have needed to start changing their batteriesafter just a year. It would beinteresting to know how many sensors fail due to battery cap seal leakage,before and after a battery replacement.
If towing, I fully recommend a TPMS, along witha rear view camera.
The piece of mind is worth the cost, IMO
No one ever said this was going to be cheap.
I first used a TireTracker several years ago whichquit working after 3-years. I replaced that with the TST which has given me no problems in the last 6-years of use. Theonly difficulty was with the programming of the unit. However, the TST people easily assisted me by phoneto finish the task. The tire sensors have replaceable button batteries andO-ring seals. Very easy to do. I did opt for the repeater that I placed on theback window of my RB and powered it from the light fixture above the toilet.Easy job. The tire pressures are within 1-3-lb. of my gauge. I used non-passthrough sensors that require a special security wrench to remove. Still easy todo. TST does offer the pass-throughsensors.
First, a big thankyou to those who do the heavy lifting on the LDO forum and make it possible fornewbies like me to read and learn from those willing to share their expertiseand experience.
I think it had a lot to do with my positiveexperience using a few of the products and services recommended by others onthis site during this recent string of unplanned LD related events over thepast couple of weeks.
It started with installing the 2nd hand TST 507TPMS that I found didn't work due to a broken antennae solder connection.
That led to an email to TST support, which promptly replied I could make a warranty claimsince it was under 3yrs old or upgrade to the latest color version for $99.
Mike Benson, firstname.lastname@example.org, said they are offering the new color monitorto existing customers at a "discount" and others if they call andask.
Ordered a new TST 507 cap set that comes with a color monitor, 4 sensors, andrepeater for $318 since I wanted 4 more sensors for the toad. Plus I sent in the old one for the warrantyclaim and both arrived within a week.
Went to install the TPMS again before our tripand developed a valve stem leak on the outer curbside dually when testing outthe new TPMS.
Dropped off the LD at Les Schwab in Elk Grovewho replaced the valve stem for free but also put on a stem that was too shortand not centered on the hole since they said that was all they had.
Left for the trip with the TPMS gadgets in thebox and minus one wheel cover since it touched the edge of the new valve stemwhen installed.
Returned to S&B from a trip and checked thetire pressure the next day and discovered the valve stem on the inner curbsidedually was broken off at the base.
Called Progressive Insurance partnered with USAAon the chance it was covered under the roadside assistance and it was. The service tech showed up at the S&Bwithin 30min of calling and put on the spare.
Called Six Robbless and ordered theDL1EC brass Dually valve kit for less than anywhere else I could find - youhave to call since they do not list the valve stems on their site. Received the tracking number via email within a couple of hours.
So, all in all, we got a ton of good info out ofthis event and trip. Found out TST now has a color monitor, good supportand warranty policy, Les Schwab has good customer service but should probablynot be the ones to install the new valves without more direction, Progressiveinsurance partnered with USAA has excellent roadside assistance - at least inSacramento area, Six Robblees has excellent customer service and prices, andthe LD can go at least 5hrs and 250mi on half a dually though not recommended.
Sometimes things go your way - whew!
