Tire Pressure

[EmptySoul]

I have never been sure about the correct tire pressure can anyone help me? The front tires are P255/35 ZR18 Max Press is 50 psi and the back are P265/35 ZR18 with max press 51. Any Help? Thanks

I have allways run 32 lbs, but have never had your tire size. Thats based on
getting even tire wear during normal street use.

I was told to always run what the door sticker says by my tire dealer. I'm running 275/40-17 up front and 315/35-17 in the back at I believe 30 lbs.

Wouldnt having low profile tires require a higher tire pressure?

 

[jeffnoel]

No the amount of pressure required is based on vehicle weight or load. My F250 says to run the tires at 85 psi. That's fine when I've got a load but when empty I run 55 psi or the truck bounces all over the road.

Correct.

Incorrect.

Correct.

For a street tire, run what the sticker says.
