2005–2013 · coupe / convertible
Every C6 runs staggered wheels, 18 inches at the front and 19 or 20 at the rear, but there are two body widths to plan around. Base and Z51 cars have the narrow body and very high rear offsets, while the Z06, Grand Sport and ZR1 have wider arches. Owners mostly chase a little more width and a flusher stance, or a lighter 18-inch track set.

Read these before choosing wheels for the Corvette: they explain the offset, fitment and hub numbers in this guide.
Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.
An owner in the CorvetteForum base and narrow-body aftermarket wheels thread runs this on a base C6 and reports no rubbing. His car has Z06 brakes, which needed a quarter-inch front spacer and longer studs, so check caliper clearance on your own car.
Konig lists 18x10 ET58 front and 19x11 ET78 rear for base and Z51 cars in its C6 fit check, under the grade where minor alignment changes may be needed.
Konig's C6 fit check puts 18x9.5 ET44 front and 18x11 ET56 rear in its no-modification range for the Z06, Grand Sport and ZR1. This is a wide-body fitment; the 11-inch rear is too wide for narrow-body arches at this offset.
Check the exact setup
There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.
Measure before ordering
A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.
These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.
Upload a photo and start with a look that suits the Corvette. Try the wheels, colour and stance before you spend on parts.
An AI preview shows the look. It cannot verify physical fitment.
These tools start with the Coupe / convertible, base and Z51 (narrow body) front size. Choose your own trim or axle in the calculator if it differs.
5x120.65 (5x4.75 inches), with a 70.3 mm centre bore and M12x1.5 wheel nuts.
They bolt on, but the 19x12 ET59 rear is 2 inches wider and sits about 45 mm further out than the base car's 19x10 ET79, so it will stand proud of the narrow rear arches.
Base and Z51 cars have 18x8.5 ET56 front and 19x10 ET79 rear. The Z06 and Grand Sport have 18x9.5 ET40 and 19x12 ET59, and the ZR1 has 19x10 ET40 and 20x12 ET59.
Yes on the wide-body cars, which are often run on 18-inch track sets such as 18x9.5 front and 18x11 rear. Brake clearance still depends on the wheel design, especially on a ZR1.
Factory tyre (tire) sizes for the 2005–2013 Chevrolet Corvette C6 are 245/40 R18, 285/35 R19, 275/35 R18, 325/30 R19, 285/30 R19 and 335/25 R20, depending on trim, with wider rears on staggered setups. Your tyre placard shows the size for your car.

140 Nm (about 103 lb-ft) for the original nuts. Confirm in your handbook, especially with aftermarket wheels or nuts.
This guide is a starting point, not a fitment guarantee. Specs can differ by market, trim and previous modifications. Confirm all sizes, clearances and fastener requirements with a qualified wheel and tyre professional before buying or fitting parts.
