TPMS

I’ve had the Trailer version for about 3 years now and it has worked well with both 50psi and 65psi tires. It does have a limit of 70 psi, but I’ve never had a problem with that.
It does read about 3 to 4 psi lower than my air pressure gauges do.
My son has 65 psi tires and the same system. No problems, either.

TAT system here also.

I did review the TireMinder website and the first line of the Trailer TPMS states:

"The new TireMinder Trailer TPMS is TireMinder's newest Tire Pressure Monitoring System, designed specifically for dual or single axle trailers running 70 PSI or less." (my bold added)

For some reason the link is not working in my original post, but it is this system...

Here is the correct link for Smart system (which does go to 232PSI as I stated):

Thank you.

Second the TST

Cant help with those. I have a TST system with the color monitor. The monitor is mall and should take up less room than a phone or GPS.
