Chevrolet Corvette wheel specs by year and trim
Factory wheel sizes on the Chevrolet Corvette
Across the 41 Chevrolet Corvette trims with a documented factory wheel, the OE diameter is 15-20 inch, width 5-10J. A forged wheel that keeps the bolt pattern and hub bore of your generation (see the table above) and matches the factory offset listed on the model page bolts on without spacers or hub rings. Going one inch up in diameter with a lower-profile tyre keeps the rolling circumference inside the usual 1.5% tolerance; every extra 0.5J of width moves the outer lip about 6 mm outward at the same offset, and each 5 mm less offset moves the whole wheel 5 mm outward.

Vehicles With the Same Hub as the Chevrolet Corvette (5x120.65, 70.3 mm Bore)
In our database, 19 other vehicle entries from 5 makes use exactly the same 5x120.65 bolt pattern and 70.3 mm center bore. Factory wheels from these cars bolt on and center on the hub without rings; offset and width still have to be checked.
5x120.65 is used by 1.6% of the vehicle pages in our English fitment guide (101 of 6,503); 63.4% of those also use a 70.3 mm center bore.
Offset and Backspacing: Factory Wheel vs Options
Backspacing ≈ width/2 + ET/25.4 + 0.5 in. "Inward" means closer to the suspension; "outward" means closer to the fender lip.
| Setup | Size | ET | Backspacing | Inward vs OE | Outward vs OE |
|---|---|---|---|---|---|
| Factory (OE) | 15x8J | ET38 | 6.00 in (152 mm) | — | — |
| Flush | 17x9.5J | ET35 | 6.63 in (168 mm) | +16 mm | +22 mm |
| Maximum | 18x10J | ET30 | 6.68 in (170 mm) | +17 mm | +33 mm |
Hub-Centric Rings for a 70.3 mm Center Bore
A wheel with a center bore larger than 70.3 mm needs a hub-centric ring. The most common combinations:
| Wheel bore | Ring size |
|---|---|
| 70.5 mm | 70.5 → 70.3 mm |
| 71.6 mm | 71.6 → 70.3 mm |
| 72.6 mm | 72.6 → 70.3 mm |
| 73.1 mm | 73.1 → 70.3 mm |
ANKUSI forged wheels are bored to exactly 70.3 mm for this vehicle, so no ring is needed.

FAQ
What is the bolt pattern on a Chevrolet Corvette?
The Chevrolet Corvette uses a 5x120.65 bolt pattern on most variants we cover with a 70.3mm center bore. Other generations use 5x120 / 66.9mm (2020–2026). Always check the exact year and trim before ordering.
What is the Chevrolet Corvette center bore?
The hub-centric center bore is 70.3 mm on the most common generation; see the table for variants. Aftermarket wheels should match this bore or use hub-centric rings so the hub, not the bolts, carries the load.
Do all Chevrolet Corvette years share the same wheel fitment?
No. The bolt pattern or center bore changed between generations, so wheels are not interchangeable across all years. Use the year-by-year table on this page to pick the right specification.
Which forged wheels fit the Chevrolet Corvette?
Any wheel drilled 5x120.65 with a 70.3mm hub bore in the offset range shown on the model guide. ANKUSI forges wheels to order for this exact specification, in 14–24 inch diameters, so no adapters or hub rings are needed.
