TPMS Settings

[New RV Chris]

What are your TPMS settings (Low PSI and temp) for dual axle TT

I am setting up my new 287BHSS.


Thanks

I use a TPMS by Truck System Technologies (TST) so my answers are biased to the information they provide. I imagine most TPMS makers have similar guidance, but possibly not 100% the same.

1. high pressure should be, "adjust the high-pressure alarm 20-25% over your normal tire pressure" (aka 114 - 119psi; I'd honestly split that down the middle at 116 psi).

2. low pressure should be, "adjust the low-pressure alarm 10% below your normal tire pressure" (aka 85psi).

Don't the trailer tires recommend 65 PSI?

I have no idea what % higher or lower you'd want but if it were me....

On the low side, anything below 60 PSI would be helpful. You'd catch a slow leak or blow out very early.

On the high side, probably anything above 75 PSI or so. Do realize that as the outside are and tire heats up, the PSI will increase. Your most accurate readings are in the morning before the tires roll.

Also, to keep things in check, get yourself an infrared temp gun. At fuel and rest stops, check the consistency of tire and brake drum temps. If one is higher than the other three, something is likely wrong with that tire, brake or hub.
