2002 YUKON XL - Max tire size?

[pete dieni]

What is the largest tire I can fit on a 2002 yukon xl. I plan on cranking up the torsion bars up front and getting aligned.

Tallest tire I've managed to stuff in the front wheel wells and turn lock-to-lock with an acceptable / barely detectable rub at full lock:
255/7018, which are 32.05" tall
Actually got more rub from 265/65R18, which are 31.56" tall
If you crank the torsion bars to give you a lil lift, you might get away with taller AND wider tires.

I had 275/60/r20's roughly a 33" tall tire on my 05 xl Denali and it only scrubbed the front of the inner fender slightly while turning and reversing.

I moved those wheels over to my 06 escalade ext this past weekend and have no Rubbing at all.
