best psi for off roading. and normal driving for 33s
I have 33"s and keep them at 34psi. Idk if its that's the right psi for my wrangler.. and I noticed that I only see wear or the part of the tire that's touching the asphalt is in the middle and not all around.. so I think I might have too much psi since its wearing around the center of the tire.. so what psi you use on your 33's! Off road and normal driving!
I run 28psi onroad and 14psi off road. 33x12.5x15 Falken Rocky Mountain ATS
2000 Patriot Blue TJ V8 ZJ front springs 2 inch BDS rear spring spacers, BDS shocks, Warn front bumper, Falken 33" Rocky Mountain ATS wrapped around 15x8 Flat black Procomp Series 51 wheels, Rampage bowless soft top, Alloy USA front axle seals, some other doo-dads here and there and more to come.
33/12.5/15 BFG A/T I run at 21 psi on highway and roads, drop to 12 or so off road.
I have done trail rides, muddy sections and climbed sandy hills at the 21 psi as well.
Different conditions may benefit from different tire pressures.

34 psi is way excessive for that big of a tire, that is even excessive for the 30" factory size tires which only take 31-32 psi. And generally speaking, the bigger the tire, the lower the air pressure it requires. For 33x12.50 tires holding up a vehicle with the weight of a Wrangler, 26-28 psi is appropriate. Something like 26 psi for around town when lightly loaded, 28 psi when fully loaded on the highway... no higher than that.

Different tires require different pressures. My tires are 33x13.50 Toyo MT which is a very stiff tire. I run 20 on the street 10 off-road and 2 in snow and sand. I have never lost a bead at those pressures and have very even wear across the tread. I have 30,000 miles on them with 1/2 tread remaning so these pressures work for me.
I run whatever is in them. Haven't checked them for a few months.
