Is 10 PSI Increase Normal After Inflating Trailer Tire to Max PSI When Cold and Then Travelling
Question:
My travel trailer has two Castle Rock ST225/75R15 Radial Trailer Tires. I have inflated them to 65 psi when cold. I use a pressure monitor to monitor the tire pressure during driving. It is not a hot day only around 70 degree and I drove for one hour. I noticed that the tire pressure increased to 75 psi and the tire temperature was around 120 degree. I am wondering whether it is OK?

Helpful Expert Reply:
What you described is perfectly okay. Trailer tires are designed to be inflated to their max psi when cold and any pressure change that occurs from driving as long as the speed and weigh ratings aren't exceeded is perfectly normal. Also the changes you mentioned are very common.
