It will ride like a Fred Flintstone car and your tires will have excess wear in the middle of the tread.

I'm running about 28psi as well. Down to 10 offroad, don't want to risk single digits without beadlocks.

i go to 6-8psi. but i also have OBA and 8 inch wide rims, its harder to unseat a 12.50 on an 8inch.

BTW when did they change the pattern of these??? mine are about 6-7 years old soi have what now seems to be the "military" pattern

I ran about 28 psi in my jeep. With 65 psi in it, take some chalk and color a section of tread the entire width of the tire. Take it for a short drive around the block. Then get out and look and see how much of the tire you are using. Then do the same thing with 28 psi and see how it looks. I was using all but about 3/4" on each side of the tread on a 12.50" width.
