Check your tire supplier before ordering wheels & tires. Below are some known available tire sizes.
C2 - 1963-1967
Mid-year Corvettes can be a tight fit, we recommend checking fitmet before ordering wheels. Body may need to be reshimmed for 9" width rear wheels/tires. Wheels with 6" backspacing may need a small spacer and seems to vary from car to car.

- 7" wheel - 4.25" or 4" backspacing

C3 - 1968-1982
The C3 Era Vettes have more fender room than the Mid-year Corvettes. You have 11" from rear inner fender to frame (measured a couple of inches above the fender lip to account for the suspension compressing). The Front wheel widths are limited by the sway bar and the frame on the backside of the frame (like in the steering box mounting area).
