Hey guys i need some help on tires sizes. I have a 2003 jetta gli and i have 18 inch rims and i think they are only 7 wide. What would the best tire size be? I have 225/40/18 on now but i think the sidewall is a bit to big. Im getting coilovers and want to go real low. I originally thought 215/35 would be good but after seeing some pics they look ridiculously small for the car.
