What Should Trailer Tires Be Inflated To and When
Question:
I have Carlisle ST225/75r15 trailer tires on my 32 ft travel trailer. The max rated pressure shown on the tire is 80psi. Should i fill the tires to the max of 80 or leave some room for heat expansion? Say 70 or 75psi. Thanks in advance for your help,

Helpful Expert Reply:
The trick with trailer tires is to inflate them to the max psi figure listed on the sidewall when they are cold and you are good. You do not need to anticipate pressure increasing from heat as this figure has already considered that.
So first thing in the morning (or before you tow the trailer for the day) check to make sure that your tires have 80 psi and you'll be good. Also be sure not to exceed the speed and weight ratings on the tire!
I attached a help article on trailer tires for you to check out as well.
