Proper air pressure

[Coinman]

How much air should you run in 35 inch BF Goodrich tires? I just bought 2021 jeep rubicon diesel and it has 26 lbs all the way around it. Seems low but is riding good. Please advise!!

If the tread is wearing evenly and it rides alright, then 26 is fine. With aftermarket tires it depends a lot on the weight of your Jeep and the stiffness of the sidewall of the new tires.

I ran 21psi in two sets of 35x12.50r15 Goodyear MTR/k’s over the course of about 6 years on my JKU with no issues. Any more pressure and I wasn’t getting good tread wear.

Philly thanks for the info. Tire ware and handling so far is great so I will stay with this unless I see uneven tread.

Wait until summer... those babies will be in the mid 30's psi with the heat. Mine vary from 29psi to 38psi depending upon the temperature. It drives me crazy because sometimes the low tp warning will go off.

Yes I live in Kentucky and this crazy weather creates many problems for my tires. Goes from low 30's to 75-80 degrees in one day. My pressure has been all over the board this year.

For best wear probably low 30s cold pressure. For best handling and ride probably high 20s. I’m in Texas too and typical pressure rise from cold tires is 3-4 psi when running.
