Got E rated tires installed, 80psi max, Tire guy said it would be better to run around 65-70 psi as tires heat up. Always thought I should run max cold rating 80psi. FW weight is around 9000 lbs hooke...
I have always said "there is no such thing as a stupid questions only a stupid person asking it” Run all or your trailer tires at max sidewall pressure. The forces implied on a tire are not always even. You touch one curb or hole in the road and you could be at a much higher load. The multiple axle system is a balance one. Just do the calculations when TT backs up a 2' hill. MM49
