All I have a 2012 Grandsport and the wheel base is 325/30/r19. Someone us selling me c7 rims and tires but they are 285/35/r19. Will they fit my car?? Thanks for everyone's help

 

Will they fit?Yes.Will they look right?No.They are way too narrow for a wide body car and the wrong offset as well.

 

The only C7 wheels that would fit would be C7 GS or Z06 wheels, and you don't want those if they're original GM.

 

It sounds like they're base/stringray C7 wheels as that was the factory rear tire size on them. It'll look like you're riding around on spare donuts, if they even clear your brake calipers.

We have a big selection of wheels specifically for your car. I also have a C6 Grand Sport and the 18x10" front, 19x12.5 rear setup works perfectly with the factory tire sizes (or wider).
