I was wondering what you guys were running your MT's @. I just got my new wheels and tires installed and they felt like rocks. So I checked em and they were around 40 psi. I took em down to about 30. Any info would be great. Heres what they look like. Thanks, wing79

I'm at 28 on my 35's. My shop put 50 psi in them and it rode like they were concrete. Soe guys on 37's run s low as 25 psi! Your 33's would need more than my 28. You can do the chalk test.

I run my 35's at around 28 PSI also, i would think that 29 or 30 PSI would be where you want your 33's.

I run 28-30 in the rear depending on weight.
And always 2 PSI lower in the front.

I run 26 psi on my 33" KM2's and have found it to be very smooth and have also run em at 30 psi and they ride a bit more stiff , so I keep em @ 26 psi

I run about 40. Is it really a big difference in the ride? Should I drop it???

By the way, your jeep looks sick with no logos and black wheels with those KM2's
And the 33's look great with no lift. I have 3.5" of lift with my 33's and the gap in the wheel well is too big that I'm actually gonna go down to 2.5" with flat fenders and 35's. Keep the all black theme going.

I think those are D rated tires (if you have the 285's), which means on a lighter vehicle like the JK you'll need less air pressure than what is used for the C rated stock tires.

A lower pressure will also make your Jeep handle a little better. It'll make it stick to the road and feel less floaty.

Having either the factory rake, or a slightly lower front pressure helps even more.

I can appreciate the ride issue with the BFGs. Even with the stock tires, running the pressure at 35 made the ride incredibly harder.

I am curious, though, about wear. At a higher air pressure for highway and city, I would think that the tires would last a lot longer. But, maybe that is an old thought.

Any ideas?

Thanks
