Right now I'm running my stocks wheels and tires, I'm hoping to get a new set, but avoid having to buy a new set of tires because there quite pricey. So my question is is will a 18x9 +30 / 5x114.3 / 73.1 wheel fit on the stock tires (08 g37 base model coupe), thanks guys. Also I'm lowered on tein h tech springs if that has anything to so with it.

 

If you have the 225/50/18s they'll be a stretched mount on a 9" rim, if they're 245/45/18s they'll be a fine.
