Tire PSI and truck camper question
My question is if the truck manufacturer (Chevy) says the max psi should be 35 (on the sticker) and on the tire it says 51 max psi, would it be ok to increase the pressure from 35 to say 45ish to acco...

If they are p rated tire 35psi will be your max load rating on side wall. Increasing the PSI does not increase the load rating. Does make for stiffer side wall though.
Also the tire gets derated some 9% if p rated.
My tires are 2435 P rated. minus 9% = 2215 lbs. Thats 4430 lbs. My axle is rated 3750.
LT tires are different. The max inflation will match the load rating on side wall.
So LT tires for my truck at 44 psi will have load rating of 2436@44
These are 4 ply. I rather have 4 ply then the p rated 2 ply.
