Rubbing will be occuring all the time even in daily driving with 33's. I have 33's on mine with a RC 4.5 lift and it still rubs on skid plate and lca's. I had the tires on factory 7 inch wide rims as well... In the back, due to the factory rim backspacing. i have less than an eighth of an inch between the leaf springs and the tire sidewall. Any tire the tire flexed or suspension flexs it would rub a little on the rear leafs. Wasn't horrible but I didnt like that it rubbed.
