keep in mind i have a 4th gen you can't even put 19's on it 18 will fit with extreme low pro's like 35 or 30 what not 17's with a bit more cusion,less weight and piece of mind this is a daily drive so I would liek to have a little piece of mind that if I run over a rock I have some padding between the wheel and the tire... unlike 18's you gotta worry about every little damn thing cause the profile on ths tire is so small..
