Another consideration. Are you running rear wheel spacers? If so, you could shorten the spacer(buy narrower spacer) so the tire just clears the rear fender. If tire is hitting frame on full compression then wouldn't be a good idea.
Just tossing it out there.
Attached is IFS rear w/ 5/8 spacer, 3.75bs rims, 63 chevys ~ 5in lift on 35x12.5 MTR. They can go a bit more into the fender, just barly miss the fender (alittle bit of rubbing) as the tire arcs up.
