sailun 637s

Just put a set of 16" on my Montana. They pumped them to 110psi. I have 2800lbs/wheel and am wondering what psi to run them at.

2800/wheel ???

I like this advise from ;

Tire Load and Inflation Ratings

Note: Towable – Travel Trailer/ 5th Wheel owners Due to the severe use conditions experienced by tires when axles are very close together – tire industry experts recommend maximum (sidewall) inflation pressure for towable tires unless this causes a sever over-inflation situation (20psi+), often referred to as the ‘basketball effect’. If this is your situation allow a 10 – 15psi safety margin above the minimum required inflation pressure.
