Tire PSI

[wowanothertruck]

What are you all running for cold psi? Door says 38 is recommended. I have the stock 35" BFG's. If you run higher or lower how did that impact ride quality and mileage?

36 f/34 r here. Rides better and doesn’t seem to impact mileage or wear much, if at all. They were 52ish psi when I picked it up.

Agreed. 36f/34r is pretty much the consensus here...

Running 36 front and 32 rear on my '19. Tires are wearing great @ 32,000 miles. Ride is good and mileage doesn't seem to have been affected. Tires will more than likely make 50 to 55,000 before changing.

Right now in Texas its a bit chilly in the mornings and every morning my low tire light comes on. It says 28-29# in all 4. When they warm up im at around 32#s. Just where I like it. Im on 37x12.50r17 KM3s. They are D rated and a little less air helps with the ride. When I had stock Cs I ran closer to 36ish.

Higher will get you better milage but bumps in the road will feel more pronounced. I run mine at 40 on street but air down to around 26 off road. Power tank ftw

My tire pressures are Cold, first thing in the morning. I also get the TPMS Low pressure if we get a fairly drastic temp change.
