My fiance is dead set on getting rockstars. She wants 20" I told her they had to be 22" if we are gonna be going with the all popular Rockstar. My question is this... she has a 2009 tahoe, regular stock height, no modifications what so ever. I have searched and seen different responses on tires sizes. I wanna know whats gonna look good under that Tahoe. Pics please if you have them. Thanks!
