Heat is the killer...
I would do 100 psi fronts and 80 psi rears..
Watch wear and ride and take from there..
Being a worry wort as I am I would probably do the rears 90 psi..
Possibly if the ride is fine I may even do 100 psi all around to make it easy... If it were my ride I would feel more comfortable at 100 psi all around.. After a trip I would probably do laser temp tests on the tires to see how hot they get...
Stay below 80 mph please....
Id rather have center wear and a cool running tire then risk under inflation and a blowout from heat at 80 MPH.. ( Front)
Not to scare you but this happens often due to under inflation..... I probably would not of chosen those tires, although I dont have a class A..
Just stating what I know about tires...
See how the right front tire blows out abruptly!!!!!! Driver could not react fast enough..
I always run max inflation when towing... But thats me...
Class A blow out
