this is what im thinking after narrowing it down.

285/60/18 in the front
305/60/18 in the rear
3/4 drop

will the 305's fit? if so what wheel width would be a good idea?

if not then im gonna do 285/60/18 all the way around.

 

A 305/60/18 is roughly a 33x12...my buddy has a set on a cranked Z71 on 18x9s and it's pretty tight. Probably have to go w/ the 285/60, they're a little shorter.

 

Im running 305-50 20's Pretty sure my rim is a 20x8. The tires do bulge out the sides but you won't have toworry about curb rash, Plus I love the look of the tire bulge!
