What doesn't leak at 60psi may leak at 75psi.

I did the chalk test
He read the door frame and sidewall.

Yeah I see what your saying but its not like im trying to push more PSI than what the manufacture shows as max.

I always go with what the door jam says (or sometimes 2 psi more). But I think like the RV is a much different then the famliy car.

Nothing will help you with a blowout. But with the TPMS you have the tire temps as well.... perhaps that would warn you in time? Perhaps.

I wish I had the TPMS when the old valve stem was leaking (unscrewed itself like 2 turns). When I left home all of the tires were perfect but then 3 hours later I stopped for a break and I check around the RV and found one of the rears was totally flat. I didnt even know it... she drove fine. So I figured the Valve stem was leaking for 2 + hours and I tore apart the inside of the sidewalls. I tighten the Valve stem, filled with air....It held fine..checked after 20 miles.... all was well for one more hour ..... BANG!!! the tire blew...scared the crap out of me. I will never go without TPMS ever again. Since then I installed a spare tire so I dont have to wait 4 hours again.
