TPMS on trailer tires

[Bendmac]

Greetings...

2016 24' FBS; came with Goodyear Endurance tires. I've been running max pressure (65#, marked prominently on the sidewall) when towing.

I recently installed an inexpensive TPMS that plugs in to the power point in the TV. This uses sending units that screw on to the trailer tire valve stems...pretty small and lightweight so no too worried about messing up the valve stems. The receiver shows current tire pressure (in bar or PSI...I use PSI) and tire temperature. (TV is a 2014 Ford F150 EB with built-in TPMS for the truck).

That said, what say ye to min/max pressure thresholds for the trailer tires? Right now I have it set on 75# for the high threshold and 50# on the low.

As far as tire temps...I hunted around but couldn't find anything to suggest a "normal" operating temperature for the Endurances. The unit only reads out in "C" and has a minimum setting of 70C (158F) and a maximum of 90C (194F). Any suggestions on what to set that upper temperature limit alarm at?

Cheers,

Bendmac

TST recommends a low setting of 10% below normal tire pressure and a high setting of 20-25% above normal tire pressure. The 25% high value would be appropriate in a hotter climate in summer, etc. Also different tires heat up more or less than others. My original Load Range E tires would get much hotter while running than the Load Range G tires I upgraded to. So you might have to adjust the high value up a bit more as you gain experience with your specific trailer/tires.

I run my tires at max pressure of 80 psi and use the -10 +25 % as stated. I often see 15+ psi increase on hot dry days...
