I just got some 315's today and they rub the arms that hold the axle in place. I had to lower the pressure to 35 in the front and 25 in the rear to make the whole tire touch the ground and hopefully wear evenly. They are on the stock rims btw. I am just wondering how much pressure everyone else is running with an empty truck. I am going to get a leveling kit also. Does anyone have a leveling kit and still have the 315 tires rub with the stock wheels? I just don't see how that will get the tires much further away from those arms to make any difference.

I put them on last week and am running 45psi all the way around....
Some rub on right mudflap when in a tight turn like going into parking space. Mudflaps are closer to wheel because of the Bushwacker Street Flares...

I've never felt it, but I can see where my left front tire just slightly rubs on the suspension arm.
Stock rims, no lift, not worried...

Oh ya, 45 psi all around.....

I've got a 2" leveling kit on. Before the leveling kit I had a little rubbing on the lower control arm on the passenger side at full lock on a right turn. The leveling kit changed the geometry just enough to eliminate the rubbing. No rubbing on the mudflaps. Took it offroad in Colorado for 2 weeks last July on vacation and for a week last October for hunting season -- no problems.
I've been running about 45 - 46 psi all around for 16k miles -- seems to be wearing okay.
