Looking for the stock wheel size (width and diameter) for a Z21? Website states “14" (35.56 cm) custom aluminum wheels w/radial tires” with an optional “18" (45.72 cm) custom silver machined aluminum wheel upgrade & Hercules RAPTIS R-T5 spare tire (must order fiberglass fenders)”. Bought my 2020 Z21 slightly used late last year and I believe the previous owner put aftermarket wheels and tires (225 / 65 R16) on trailer. My trailer has fiberglass fenders. The clearance between the tires and spring hanger clips are too close for my piece of mind. I just completed the Dexter suspension upgrade but still have a clearance issue. My only options are wheel spacers or change out my rims / tires. Anyone installed wheel spacers? If so part number / link would be helpful.
