With 225s on 7 X 15s (5 inch back space) &-2 camber, the tires hit the inner fender in the rear. A 7mm spacer took care of that......then I needed longer studs. OK, this is all simple stuff, right? With 10 X 16 & 10 inch slicks (same backspace & camber), I have clearance to the rear inner fender without the
spacer. Why?....cause the tire doesn't stick out past the inside edge of the wheel. I needed new rear fenders, of course, but that's not important now.....
WAG at Joe's set-up (8 inch wheel, 4.5 backspace) is he won't have clearance issues to the inner fender, but the fender flaring is really going to be a challenge. Hammer, dolly and 15000 whacks
Now lets look at the front end...
There was no way the 225s & 7s would work up front without flares. To check for clearance, ya gotta mount the wheel/tire , disconnect the sway & T bars and compress the suspension to the bump stops......then turn the wheels lock to lock. At static height, it looked fine. Compressed, it wouldn't turn but about 5-10 deg.
On mine, not only did I have to flare, but also I reshaped the opening by moving it up .75 inch (ya can't hardly see it).....got an in progress pic somewhere.hammer/dolly & 10000 whacks per side
