Biggest tires W/ 18's
I recently bought some 18 "by 8.5 wheels and I was wondering what is the biggest tire I can fit front and back ? I'm wanting something around 28" tall and somethin as wide as I can get on the back without rubbing .. I'm at the factory ride height w/ new shocks and springs .. And my buddy has a fender roller if needed :-D also thought about removing the rearend bump stops . .. Ima try to go with BFG or nitto or Mabey even MT street comps ! Thanks ppl !

You will be limited to around 255-265 tires with 8.5" rim. Not sure whats available in 28" diameter. Nitto has a 255/45/18 and a 275/40 that may squeeze on.
