Default Matching sidewalls?

I just put 315/30/18's in the rear and coupled with the 275/40/17 up front, it looks rediculous... What tires should I get for the front to even out the sidewall appearance with the rear? This is for the stock 17" & 18" set up.

Should be within 5 of the aspect ratio.

Ex: 245/40-17 & 275/35-18


You need 35's for the front with those rears or get 35's for the back with those fronts.

I would suggest 295/35-18's for the rear.

^^


If your ratio is gonna be 30 for the rears, you need bigger wheels to hide the wheel wells. 19's or 20's

With a 17" front...you will not find a tire with as little sidewall as your 315/30 rears have.
A 245/40/17 is about the shortest tire available that will fit a 17x9.5" wheel.

If you had 18" fronts, a 285/30/18 would be a good match for those rears.

Go with a 315/35/18 in the rear. That will increase the rear diameter and get you away from potential Traction Control issues.
