if you have a 4'' leveling kit yuo should be good on running 35s, try to get after market wheels so the back spacing will push the tire out of the well. (that is back spacing exlpained easily) i have a stock height 1st gem clearing 35s with out issue

 

Could be bearings.

 

X2 on wheel bearings. They will grind/growl at you when they are bad.

 

4 inch lift can fit 37's....a 2 inch levelin kit will clear 35's

 

I have a 2inch leveling kit and my 35's clear just fine. The only time I have had them rub was when I was out in the desert having fun and hit a steep incline from an angle the same time I was turning. Other than that they are no problem at all
