Chevrolet Colorado — Bolt Pattern

The Colorado has changed bolt pattern twice: 6×139.7 on the first-gen GMT355, 6×120 on the 2015–2022 mid-size truck, then back to 6×139.7 on the 2023+ generation — different center bores each time, so wheels don't interchange across generations.

Common questions

What bolt pattern does the Chevrolet Colorado have?

The Colorado has changed bolt pattern twice: 6×139.7 on the first-gen GMT355, 6×120 on the 2015–2022 mid-size truck, then back to 6×139.7 on the 2023+ generation — different center bores each time, so wheels don't interchange across generations. Check the table above for your exact generation, and confirm against a wheel or the owner's handbook before buying.

Will other wheels fit my Colorado?

Only wheels with exactly the same bolt pattern — bolt pattern has no working tolerance. The centre bore must also be equal to or larger than the hub (a larger bore just needs spigot rings). A different pattern needs bolt-on adapters, which also push the wheel outward and change the track.

What is the centre bore on a Colorado?

78.1 mm on the current car — earlier generations may differ, see the table. The bore is the hole in the middle of the wheel; it has to clear the hub spigot or sit on a spigot ring.

Bolt pattern is only part of fitment. The offset (ET) decides where the wheel sits in the arch — work that out with the wheel offset calculator. For tyre sizing on a new wheel width, use the tire size calculator.
