Per GY Tech Support when up sizing. Weigh each tire with RV fully loaded. Use the weight/inflation chart then add 5 psi. Better ride better tire wear better braking.
I ran 85 psi on GY G's thousands of miles with perfect wear.
That is what the inflation charts are for.
Don't believe me call GY Tech support.
This is exactly true, weighing each wheel position will give you the numbers you need to utilize the weight/pressure charts. Without knowing what every tire position is carrying your only going to be guessing as to the correct tire pressures needed to carry the load safely. Just because that tire is designed to have a cold inflation rate of 110psi,that can then carry 3,750lbs that may not be the correct tire pressures for your situation.
They recommend inflating to the highest pressure on each axle.
