What year is your Jimmy? I have a 87 and am about to put a 4 inch on 35s. the 35s will fit but i wont be able to crank fully for turns but its totally worth it. If ur putting a 4 inch then 33s will fit easy
i have a 1999 gmc jimmy sls, i have a set of 31's on her right now and she only rubs when i crank the wheels all the way left or right, the back tires dont rub at all, i was told just to get a set of wheel spacers with a torsion bar and shackel lift and all my problems would be solved, but i have yet to try this
