I run a 2-4 psi difference between the front and rear of my Jeep. Front 26-28/rear 24-26. But thats with 35" mud T/A`s. I also keep a close watch on the pressure, usually check once or twice a week. Never had any wear problems. I also rotate every 3-5000 miles. The Buckshots are a good off-road tire, but I haven`t seen a set yet that was any good on the road, they all ride like crap.
