Tire Pressure

[Smitty00Z71]

My truck came with 265's .... however the last owner put 285's on the truck.. which is fine. Question is, do I run these 285's at the PSI noted on the tire ??? it says max 65 psi cold - that sounds real high.

 

I know the stock 265's are supposed to be run at 35 psi as indicated on the sticker on the door. But didnt know for sure if I should be running these 285's at 65 psi

 

thanks,

65 psi is the MAXIMUM pressure, not the recommended pressure. The number on the door sticker would be a good starting point. One way to check if you're running the right pressure, is to rub a line of chalk across the tires, and go drive around the block (don't hit anything wet ). If all the chalk wears off, you're pretty much good. If only the center section is worn off, let some air out, and repeat.

I keep my 285 bfg's at 52 psi.

good tip ... yes, I have 50 psi in them now

[Smitty00Z71]

what does everyone else with 285's run for PSI?

[Ranger]

40 to 45 psi, but mine are Load range Es, max pressure 80 psi.

I had 285's on my last truck and I always ran 'em at 35 psi. Wore just fine
