TPMS Tire pressure monitoring System

[rtate]

I just installed A TPMS System and noticed that If I leave the monitor turned on and leave my trailer, the monitor continues to report the last temperature and pressure it received when I was hooked to the trailer.

This is telling me that when towing, if it loses contact with a particular tire it will act like it is transmitting reliable data when it is the last temperature and pressure it was able to read.

This is very misleading. You could actually be running on a flat tire and the monitor is telling me everything is ok.

Is there a way to change this maybe thru a default setting?

I bought an AMERICAN MADE ...INSTANT reacting unit
Pressure Pro RV 360.
Made in Ohio....it uses radio signals and if I dont turn the trailer part off... it almost instantly says I LOST A SENSER when I drive away from my 5er.

Getting the CORRECT UNIT is a big part of any purchase

I reasearched the heck out of them BEFORE purchase.

Unfortunately I think most TPMS operate as you're describing. If they're maintaining radio contact they are reasonably quick to inform of issues such as low pressure, overheat etc. If they loose signal, it just reports last received signal while waiting for an update. In this situation it takes about an hour for it to report a fail. If you simply get intermittent signals, with temporary reception every thirty minutes or some other value less than an hour you'll never know you have shoddy reception. I put a repeater on my TST 507 system because of this but I still don't really know if I'm getting a reasonably consistent signal or not.

If that is the case, then what's the purpose of even having this unit? Tire blows out, and one might not know about it for an hour ?

You're overacting to a non-issue.

I have used the Tireminder system and it did the same thing.

When the unit powered up, if it did not read any sensors, the readings would lock and only occasionally go blank. If it picked up just one sensor, that one would go live and the other 3 blank.

I would often lose the signal to one of the rear trailer tires and it would report immediately. If I gave the receiver to my son in the back, that 5-7 feet distance change was enough to quickly regain the signal. I needed a repeater or booster to fix this, even though my TT is only 26' bumper to ball.

There is very little delay when you are actually driving and its sensing at least one sensor...or not.

It may be a non-issue with a Tire Minder, it is not a non-issue with other brands.

So I guess I have to wonder then, when a tire goes flat, what happens first:

1. You hear the TPMS sounding the alert

2. You hear the BOOM from the tire exploding.

3. You are flagged by a passing motorist.

It appears there's a 33% any one of them would be the first notification of a problem.

Wow! When I was considering A TPMS I asked for advice on which brand to purchase. The response from most everyone on this board was TPMS. After purchasing mine it appears no one likes their TPMS.

Oh well. I guess the advice was worth what I paid for it.

What you're saying is unclear. You repeat TPMS when I think you're referring to your brand name. TPMS means T(ire) P(ressure) M(onitoring) S(ystem). Could you specify what brand you have, i.e. TST, Tire Minder, Pressure Pro, etc.?

I think saying "it appears no one likes their TPMS" may be overstating the issue. I like my TST system, but I don't like the issue of lengthy response time for signal loss. TST seems to be the best of the bunch, but, alas, it isn't perfect.

FWIW.. TPMS is a generic term for Tire Pressure Monitoring System.
TST is Truck System Technologies... A manufacturer of a TMPS.
We have a 10 sensor TST 507 system with non flow thru sensors and a repeater for our 33' fifth wheel and are ecstatic with it.
Towed 12k miles in the last 11 months and haven't had any problems with it. We received a few temp alerts, but that was due to improper, initial set up. Wouldn't be without it.
If you did get a TST TPMS and have concerns, give them a call. They have outstanding customer service.

That's what happened to us, we knew a tire was blown when a passing truck signaled us that there was something wrong. We have the TST system and I have lost faith in it.

Without knowing your brand and model, we can only generalize. If you had only one sensor your scenario could possibly exist, but when moving the sensors update the info quite frequently. If one sensor updates, the software expects all of the sensors to update. If one does not report a flag is set to notify that the sensor is missing.

That should be the way they work, but not all work that way. Some have a time period of up to an hour after they fail to receive a signal before they report that loss of signal.

Is this system wired? Unlikely, it is probably wireless and uses a radio signal. So even if the trailer is unhooked you may still be close enough to pick up the signals from the trailer tires.

The brand is TPMS, model 536. I drove fifty miles away. Don't think it was still picking up from the sensors.

Probably not....heh. We have the TPMS and I have not been too pleased with it.

Which one did you get?
I wouldn't think it should report anything. Most MH's actually have to use a repeater to get the signal from the vehicle that's being towed.
