Ok, revised to include the big boots and 1.4:1 T-box. Those 255/85/16's must rub the fender wells no?
Actually they didn't with the lift I had. They are 33" about. The front bumper may need to be trimmed if it's stock but my truck at least is way beyond that. If I recall, the 255's didn't even rub the radius arms but it's been a while since I had that size tire. The 285's will definitely rub the arms.
The 18" tires I am running now rub the arms and I had to trim the plastic rocker covers some since the tires will rub there when it flexes.
If I ever get around to getting sliders for this thing I may have to trim them also.
Peter, I just remember how my 255's had to stretch a bit to fit 8" rims. I can get it about higher pressure on 235's, I don't think I would want to air them down much.
