20x8.5 with a 245/30/22 tire and roll the fender u shud be okay.. and if anything go to autozone or kragen or o'reily's idk what its called in your state. but get some rubber coil spacers. and it will stiffin up the springs and it will not bounce as much over dips and bumps. and u can do this your self with any regular lift jack. i had to do this on my maxima that i just got.because the rims are 9.5 inches wide running a 245/35/20 tire..and with people in the back.. jjust going straight on level ground it would drag.so i lifted it with those spacers about 2.5 - 3 inches no rub what so ever.. and it doesnt have that saggin look. how u see cars going down the street the front is all super high and the back the fenders are covering the wheels. but my car sits even..
