I have the TireMinder T66M and absolutely love it! I will never travel without a tire monitor again.

Thumbs up Tire monitoring system...LIKE IT A LOT!!!

Definitely brings peace of mind! I would rather have the opportunity to avoid a blowout with an advanced warning if possible! Saves me a world of hurt - literally - should the tire blow and I flip my rig! It isn't a 100% guarantee, but we think it's better than no warning at all!

Got them installed now. One thing the tech at the tire shop and I noticed immediately when demonstrating how far they stuck out from the wheels was that with the sensor screwed on to the rubber stem, there was a constant air leak. We tried a couple of tires and they both leaked.It was not a problem since I was bringing in the wheels/tires to have metal stems put on anyway to avoid damage from curbs/rocks or whatever I might clip in our travels.

2nd thing was trying to actually find a valve stem that would work on the 13" Sendel wheels that come on the X20E as I wanted a 90 Degree stem to bring the sensors closer to the center of the wheel. Luckily a rep was in that same afternoon and he recommended the stems which the Tire shop installed once they received them. Sadly, they mount with a rubber seal in the Wheel hole which means there is still a tad bit of flex, but likely a lot less than with a rubber stem. I am hoping the centrifugal force while travelling is somewhat negated in this orientation. I will have to see how this performs on our up vacation where I suspect we'll be putting on about 1500Km.

Here are a few shots.





I do have a question although it's not a real clever one, LOL
The tires on the rims are TOW MAX. 13" The PSI rating is 51. The TST monitor only allows me to set a High Alert PSI to 101 degrees at it's lowest setting. I would have liked to set it to something like 60 PSI to alarm on but can't so does everyone in this situation just ignore the small detail and simply watch for a HIGH temp reading around 60PSI on the display?? It's pressure loss that is my main concern so the low PSI alert should be fine. I set it to 47 PSI until I get a feel for this system.

Also, what might a reasonable Temp warning be for these dinky tires? 120 Seems high if even attainable before a melt down otherwise the sensors seem to be displaying PSI properly +/-1 lb from my air compressor tire gauge. In other words I pump in 51 PSI but the sensors show 50 which is fine.

Don't sweat the temp warnings. The pressures are what are most important. If you have the PSI right and the unit is not overloaded, the temps are not a major issue. Ive had tire temps run as high as 125 degrees on really hot days. If you don't keep your psi up where it needs to be, thats when you really build heat and run a risk of tire failure. I did a little research and found that in the desert southwest, tire temps. will run as high as 140 degrees at higher speeds on hot days. Overload and tire pressure is what is important. Tire temp will take care of itself if the other two are looked after.
The TPS that I use sends out warnings at 15% plus or minus where you set the limits. Rapid air lose happens much sooner!!

For those who have experience with TPMS how much PSI rise do you see on hot days under normal conditions?

My tires are 50 PSI cold. On a hundred mile run with 90 degrees ambient temp I typically see a 4 - 8 PSI rise in pressure. Physically checking the tires everything is OK.

Would like to hear other's experience with pressure rise.

Thanks.

65 psi cold. 74 psi hot is normal for us on 90 degree days. Did have them reach 81 psi on a day that was 105 degrees last year!!

Tire Pressure Monitoring System

First off, I would be more concerned about the tow max tires but the TSPS system will be a great help.
As for pressure and temps, I have E rated tires at. 80 psi. I notice the psi run approx 10 psi more when constant running. Often more.
Temps are usually 10-20 deg F above outside temp. They run a little cooler at highway speed and when you stop at a rest area they will go up a few deg due to lack of air movement. Mine are alarmed at 158 deg.

The alarm parameters are what they are with your system.
I find myself scanning the display just like scanning the mirrors and gauges.
BTW, best money I ever spent Rving.

I was just reading up on that. DW would freak if I even mention tire replacement at this point after all the new toys I have bought to go along with this trailer, not to mention hand packing the wheel bearings. I'll see about a replacement next year or sooner if I spot a deal but thanks for mentioning the Tow Max issue.

When setting the high pressure setpoint, you need to set the low pressure setpoint first and then go back and set the high. When cycling through the parameters, you get the high setpoint first and it does not allow a setpoint higher than the low. Took me a couple tries to figure that out. Now that you have the low setpoints at 47, you can set the high for 60 -62 psi.

So far we have seen at most a 10 psi rise in tire pressure. Temps vary a lot based on sunlight exposure so I left the warning at 158*

Brilliant! Worked like a charm. Thank you.
