Try 35 psi, don't go over that though.

idk about the chalk test, but when i got my 235/75's the tire shop aired them up to 40psi, i later dropped them down to 30psi cuz the jeep sticker said so... i think i typically try and run my tires between 32-35psi, but i tell ya what, my bfg mt's dont care if it has 30 psi or 40 psi, i still get the same general mpg out of them...
Stock Tire Pressure for my '96 XJ is 33 psi and with my added Build and OffRoad Equipment's Weight I keep mine at 38 psi and my Tires seem to be Wearing Evenly.
If you Truly wish to get the Tire PSI Correct for your Vehicle, Look at this. IMHO

You want a flat contact patch for best MPG results and the best way to achieve that on any given set of tires ( NONE ARE THE SAME ) is to do a chalk test!! :thumbup:

I know you all are going to bring on the flame here... but oh well..:flame:
Since long before I got my XJ, when I drive Highway, I run 50 to 55psi. Yes that is higher than the max on the side of the tire. Bite me, I have over 200,000mi of Highway time on 'over inflated' tires, and I have never had one blow out or fall apart yet.
The handling on over inflated tires does not suck. DUH! it makes on road handling better just like low profile tires and large rims to. it takes the marshmallow feel out of the steering wheel and has very good Highway results.
The ride does suck on bumpy roads you feel it more, but a lot of highways are smooth enough that it doesn't bother me.
Tire wear?
Am I the only person that notices that most peoples tires wear on the outside first? What is all this "the center of your tire will wear out" or "tires wear funny" c'mon. If your that dead set against it, you never have done it, and don't know JACK...
I won't recomend running above the side of the tire, because it will void any warrenty that the tire has, and I don't want to be liable for telling you to do it.
But Its not going to change the direction the world rotates, or cause a hiccup in the space time continuum. That only happens when you go 88MPH with 1.21 Gigawatts of energy.

You see the outsides wear first, because most people who own a car don't know diddly squat, and don't know when their tires are underinflated.
I'm sorry, but YOU don't know jack if you don't think the center of tires won't wear out while over inflated. I've seen it first hand, from ATV tires to truck tires. I've seen MTRs with bald centers, and tons of tread on the shoulders. It does happen.

Good, so you have seen tires with bald centers. Would you like an award? You are now, just like every other person in the world. Congratulations on your observations.

On normal road tires, I always run the max recommended on the tire. Larger off road tires may be different. You do have to watch out for wearing out the center, but I like to corner fairly fast, so the fronts tend to wear out on the edges. And rotate the front to the back. This approach will maximize your gas mileage. Another interesting approach I read in this forum is to put a paint stripe across your tire and see if it wears off evenly. I also like the high pressure because we have a lot of huge potholes. The higher your pressure, the better chance the tire has to not bottom out on the rim to cause a destroyed tire and bent rim.
Well here is my 2 cents! I was running a set of MTG Retreads at 42 PSI hoping to decrease rolling resistance a tad and bring my mpg up. Only my xj turned into a shopping cart! The few $$ I could save on fuel is not worth beating the hell out of my kidneys. Tire was rated for 85 PSI but I believe it is more important what the vehicle recommends.
