I had 285/75r16 bfg at's mounted on 7. 5 rims. They looked a little balloony, as this is the smallest rim they were rated for. They did look good on the truck though. I normally ran 58 psi up front and 52 psi rear, rotated them every 7000 miles. After changing them with 28000 miles, they were only half worn out. I had my steering box replaced at 34000 miles, 15000 of them had the 285's. Were the tires at fault? I don't know, but after switching to 255/85r16's, no more front end wander, no more steering effort, and the truck tracks perfectly. The new tires are about the same height as the 285's, but 1 inch narrower. No problems towing (7000 lb. TT) and so far no problems in the sand(my reason for going from 265 to 285 originally). I switched from at's to mt's. So far I'm very impressed. No more spinning the tires and getting stuck on grass, no more rocks flying all over the place, no more sinking in mud. At 17 lbs. they handled the ocean dunes pretty well. They even grab the blacktop better, wet or dry. Just my . 02, good luck.
