The path of the Jeep wanders or the cab is swaying? 50 is insanely high haha. I run mine around 28-30.

 

I only have 35s and i ran them at 38psi and i was all over the road. I dropped down to 32 and now im golden. I should probably go even lower but im feeling this out for now

 

Well see...... I had a blow out with one of my tires(believed tire malfunction). My dad asked me what pressure I was running and I told him 35. He looked at the tire and said I should be running 50. I TOLD him that that's too much but he insisted that I do it cause the 35psi caused my blow out. YEA RIGHT. He proceeded to fill my tires and I said whatever I'll give it a try. Thanks got the info guys..... I'm going to go let some air out :crazyeyes.

 

yup, I run my 35's at 28PSI and have very even wear. The tires are meant for a heavier vehicle, so the tire pressure specs on the tire don't match the application.

 

I run 30 to 34 lbs in mine with no issues at all. To my best guess, I figure the tire's rubber compound my be different than others. What tire make to you have and how much weight you're adding by adding aftermarket products. You just have to play with them and get them to ride right by drawing a chalk line across them and reading the line. If is gone in the middle then the tire is too full, if it's gone on the outter edges the tire pressure is too low. If it's gone all the way acrossed the tire then it's properly in flatted. And never fill a tire to max pressure! Hope I helped.

 

My BFG 37s also at 26 psi. Above 30 they get squirrely. The pressure listed on the tire sidewall is a maximum and the pressure at which you can safely load the tire to it's max load rating which is hugely high.

Yeah, the 50 psi number refers to the max the tires can handle. Remember, these things don't just sit under JKs (I know, I know, sometimes it's hard to remember there's anything else out there).

For example, the stock BFGs that come on Rubicons have a max PSI of 50. It's only by looking at the door that you see you should only have them at 37 for a Jeep. Try airing those things up to 50 and go for a ride. Veeery exciting

There's a variety of tricks you can supposedly do to figure out the right pressure, mostly centered around chalking or wetting a perpendicular line across the tire tread and then driving a few rotations in a flat dry parking lot. The line should transfer to the asphalt clearly and evenly. If it's only in the center of the tread, you're over inflated; if it's only on the outsides, it's under inflated.
