7 years. Still not a record.
Anyway, the MAX PSI listed on any tire's side wall is the maximum PSI that can be used. It should be used when doing heavy towing/hauling. It can be run daily, but ride quality will suffer.
And just as an update. I ran those 285/75-16 BFG AT KO's for 60,000 miles with no issue and then sold them. (2007 I think)

 

I have rubbing on mine when I turn hard I have 01 screw wit 2857017 on 17x9 wheel factory height with just a slight turn of the torsion bars. Procomp shocks all new front end.

 

You need more lift, smaller tires, or a narrower wheel if you want less or no rubbing.

 

My question is.....
Should I run a lighter PSI on the front as opposed to the rear since it's a RWD? And if so what do you think? 40? 45? 50?

I'm currently running 65 PSI all the way around and the ride is terrible.
Just put the tires and rims on a couple weeks ago.
I'm thinking I might run 45-50 PSI with Nitrogen instead.

Any comments on it's effectiveness?

Trucks 10 years old, original parts are worn-wearing out, doing a pretty much complete overhaul of the suspension system.

Maybe new Front spring coils will help?

 

Front springs? Is it a 2wd? My 4x4 has torsion bars no springs though
