I had -2 offset on my Borbets and 265/60-18s with stock height, no lift.....and quite a bit of trimming. Had to pound the rear part of the front wheel well and pound back the bolt there....and cut out most of the fender liner, and they stuck out about 1/2" from the wheel well. With a -10 you're looking at at least the same amount of trimming and sticking out even further.
