About TPMS Systems

[Ron & Izzy]

quick question... as a newbie.. i'm wondering about tpms systems, and cost versus quality.

1. systems are all over the board in pricing.. from $50 on up.
2. the systems i see recommended are in the $300+ arena. is this due to reliability, length of transmitting, console, ...?

i'm just trying to get a grip on the differences between the units and their corresponding costs.

so... just tryin' figure all this out. i'm picking up my 3121 on the 16th, so i could pre-purchase the tpms and install it when i pick it up and doing my pdi.

i did a search.. so hope i'm not lol

thanks in advance,

ron-

This has been discussed a lot here but especially on the Keystone forum. You can probably find info by searching for "TPMS" in the search function above.

That said, I think that like any electronics you can find a broad range of products and prices. Sometimes a cheaper, off-brand solution can work. But it's usually the more expensive, tried-and-true solutions that get the larger following.

We used a Tire Minder TPMS for a couple seasons. I got tired of the many false alarms or disconnects. We upgraded to the TST 507 which I learned about here and seems to have the broadest following. So far it's been rock solid. That would be the system I would recommend.

We've used TST 507 for most of our 11 years of full timing.

I bought TST 507 system and used it for the first time on our recent 2 week trip. It worked great and gave me peace of mind while driving. I did get 3 alarms...the beeper goes off and the affected tire flashes the temperature and pressure. Each alarm showed something like 320* but normal pressure. I pinged this forum group with a question about "phantom alarms" and the most likely culprit in my case is that I have an atomic clock sensor mounted in both propane closets (one clock is in the front bath and the other is in the living room). The alarms are scary at first - but when I saw the ridiculous temperature flashing I silenced the alarm. For the first one I turned the monitor off and on and it came back with normal readings. For the last two I just silenced the alarm and after a few minutes it resumed normal readings.

Like DQDick stated - I think I will be able to use this system for many years. I think it is well worth the cost.

Another pleased TST 507 user here. But friends have other systems they like. My only complaint about the TST system is the color screen is hard to see in sunlight. I now mount it off the sunroof (and then close the cover) to get it into more shade.

Csrl n Susan. Did you take the screen protector off the screen? I had the same issue. Called the company and he asked me the same question. There is nothing in the directions about removing the screen protector. The customer service guy told me the three previous calls he had to mine were the same issue. There is a very small tab in the upper right hand corner that is easily missed. Peel it back and take off the screen protector. Mine is now plenty bright even in the sun. .

I bought a TST system at the rally in Sept. I'm a very happy camper.

We had the TST507 for 10-12 years. Never got any alarms for temp or pressure. Never had a low tire an alarm. Did occasionally lose signal to a sensor or two until I added the repeater.

I have a TireMinder A1A and it has been great for 5 years.

Need help. My TireMinder is going off on High Pressure (all 4 tires within 15 minutes from cold)
1. Tire gauge says 110 at tire (cold) Tried 3 different gauges and each close to 110
2. TPMS display says 120 (cold)
3. Just tried 2 new tire transmitters and they read 120 at the display
4. Took a transmitter off an RV tire and put it on the truck. Showed exactly what the truck said.
I’m stumped! Need a new set of brains on this. Thanks

What is your high and low pressure alarms set at?

Sounds like you just need to raise your high pressure warning setting. I would not be real concerned about the 110 vs 120 reading.

[Kris & Al]

TireMinders are set at 20% above tire set point. Tires are 110psi so hi goes off at 131psi. Tires will go up from there 4-6 psi.

My real problem is, where is the problem. Tire senders, Display logic or gauge. Gauge seems OK vs other gauges. Display seems OK when I take senders off RV and put on truck (reads exactly what truck display says). All 4 senders couldn’t have gone bad at the same time plus 2 new senders read the same.

Could change the tire setpoint to 115, so hi limit goes off at 138and fix the problem I suppose. But how high actually damages my Sailuns? Plus high pressure could cause wear problems and a rougher ride.

TST is the overwhelming choice of the people we know. Great quality, continual improvements and great customer service. We have been using TST since 2010.

Ron I would check but I believe all the new Montanas come with TST system already installed on your rig. So no need to buy one. TST is a good TPMS that is what I run and love it

Nope, not an option from the factory on the 2021's. Standard equipt now on the 2022's. Check with your dealer, they may offer some kind of discount for a year in their store with each new RV purchase, you never know. Our dealer did, but unfortunately, at their regular price, even after the discount, several things I wanted were cheaper on line. including the TST. Good luck with the new trailer.
