Tire PSI question

[They call me Pete]

Do you use door jamb sticker or tire ? Tires say 80 psi max and door jamb says 55 psi fronts and 80psi rear. Front seems it should have more carrying that diesel

I have always went by the door and than added a few pounds. Tire rating is max for that tire in general regardless of vehicle it's on.

Like stated, tire is max. Door is for oem ratings. Stock stock stock.
Run em up to operating temp, mark a chalk or paint line across em, drive a few revs or until the line wears.
Wearing in middle is too much air.
Wearing in sides is too little.

I made my Samsung SGH-I997 send this.
