Tire pressure question

My current tires are BFG AT's (31x10.50R15)

The max cold pressure is 50psi but I'm curious what pressures you all drive on the road with. Do I just fill it to max or is it advisable to stay a few lbs below? What if I drove it at 30-35psi - would I notice a difference in handling or excessive wear on the tire? I've read of people airing down when driving offroad but I'm mostly curious about on road driving.

holy crap don't use the max pressure, that has nothing to do with how much air you are supposed to use, that is just the max for that tire. 98% of vehicles out there run between 30-35 psi. with bigger tires most guys lower it around 30 or a little less for a smoother ride. anything more than 35 is too much for a normal vehicle, excluding trucks and tow vehicles.

"The danger to America is not Barack Obama but a citizenry capable of entrusting a man like him with the Presidency. It will be far easier to limit and undo the follies of an Obama presidency than to restore the necessary common sense and good judgment to a depraved electorate willing to have such a man for their president."

whoa never run at max pressure. that only says what its capable of handling.most car, trucks, and vans run between 30-35 psi. some even run as low as 26. the only ones that run over 50 are work vans and trucks such as 3500s.

50 psi is way out of line, try 30-32. Personally, I run 32 psi, even tho it is a bit higher than my tires need.

I ran my 31's at 28 psi, too. Put a chalk line across the tread, roll over it a time or two, see how it wears. Adjust accordingly.

30 psi up front and 28 psi in the rear when I had 31x10.5R15s on my TJ. 24 psi on my YJ for 8 months out of the year when I lived in upstate NY. InfernoGirl has got it right IMO. Whatever pressure puts the treat on the ground flat and even. If the chalk line wears off the center first you have too much pressure. If it wears off the edges first you are too low.
