The 2020 Chevy Colorado Bolt Pattern: Exact Specs & Fitment Guide
If you are looking to upgrade the wheels on your 2020 Chevy Colorado, getting the exact bolt pattern and hub measurements right is step one. Guessing on wheel specs doesn’t just lead to wasted money and return shipping—it’s a serious safety hazard.
Here is the straightforward technical data you need to ensure your new rims fit perfectly, look aggressive, and handle exactly the way they should.
The Quick Answer: 2020 Chevy Colorado Wheel Specs
- Bolt Pattern: 6×120 mm (6×4.72 inches)
- Center Bore: 66.9 mm
- Lug Nut Thread Pitch: M12 x 1.5
- Standard Torque Spec: 140 lb-ft

Generations Matter: Why Colorado Fitment is Tricky
Unlike some trucks that keep the same hub layout for decades, the Chevy Colorado has a notorious history of swapping bolt patterns between generations. If you buy a set of used wheels off Facebook Marketplace simply because they say “Chevy Colorado,” you might be in for a rude awakening.
Your 2020 Colorado falls right in the middle of the second generation, which uses a highly specific layout.
| Truck Generation | Model Years | Bolt Pattern | Fitment Notes |
| 1st Generation | 2004–2012 | 6×139.7 mm | Shared with Silverado/Tahoe; massive aftermarket. |
| 2nd Gen (Yours) | 2015–2022 | 6×120 mm | Requires specific rims; fewer direct-fit options. |
| 3rd Generation | 2023–Present | 6×139.7 mm | Reverted back to the older, more common standard. |
Because the 6×120 mm pattern is relatively uncommon, double-check that any aftermarket wheels you order are specifically drilled for the 2015–2022 model years.
Understanding Offset and Stance
The factory offset for a 2020 Colorado typically sits between +25 mm to +33 mm, keeping the tires tucked neatly inside the fenders. When upgrading, offset dictates how your truck will look and perform:
- Lower/Negative Offsets (e.g., 0 mm to -12 mm): Pushes the wheel outward. This gives your truck that aggressive, wide-stance look and improves off-road stability. However, pushing the wheels out too far can cause tires to rub against the fenders or cab mount when turning, often requiring a leveling kit or minor trimming.
- High/Positive Offsets (e.g., +25 mm): Keeps the wheel tucked in close to the suspension. This is great for smooth city driving and keeping mud off your paint, but limits how wide of a tire you can run on the inside.
A Warning on Wheel Spacers
If you want a wider stance but want to keep your factory wheels, wheel spacers are a popular route. However, safety is paramount here.
Never use generic, lug-centric spacers. You absolutely must buy hub-centric spacers drilled specifically for a 6×120 mm bolt pattern with a 66.9 mm center bore. This ensures the weight of the truck rests on the stout hub lip, not on the wheel studs themselves. Using mismatched or cheap cast spacers (like trying to force a 6×5.5 spacer onto your 2nd Gen) is a guaranteed way to shear a lug stud on the highway.
Installation Best Practices
To make your new wheels feel like factory equipment, keep these installation rules in mind:
- Hub-Centric is King: The 2020 Colorado has a 66.9 mm center bore. If your aftermarket wheels have a larger bore (like 78.1 mm), buy a set of polycarbonate or aluminum hub-centric rings. This eliminates highway vibrations.
- Use the Right Lugs: Factory Colorado wheels use an M12x1.5 thread pitch. Ensure your new lug nuts match the “seat type” of your new wheels (conical vs. flat seat).
- Torque to Spec: Tighten your lug nuts in a star pattern to the factory specification of 140 lb-ft using a calibrated torque wrench. Always re-torque them after the first 50 miles of driving.
Conclusion
Choosing the right wheel specs prevents fitment headaches and keeps your truck safe on the road.
Upgrading a Chevrolet Colorado means checking the bolt pattern, center bore, and lug specs for your generation. Confirm these before ordering rims or spacers to avoid returns and extra price.
Pick tires that match diameter and offset so the speedometer and fuel use stay accurate. Verify fitment for brake clearance and suspension travel.
Maintain proper lug torque and inspect wheels regularly. Simple upkeep extends tire life and protects studs and bearings on all vehicles.

Frequently Asked Questions
What does 6×120 mm actually mean?
It means the wheel hub has 6 lug nuts, and the diameter of the imaginary circle drawn through the center of those lugs is exactly 120 millimeters across.
Can I put Chevy Silverado wheels on my 2020 Colorado?
No, not directly. Most Silverados use a 6×139.7 mm (6×5.5″) bolt pattern. To run them on a 2020 Colorado, you would need a heavy-duty set of wheel adapters that convert your 6×120 mm hub to a 6×139.7 mm pattern.
What is the factory center bore for the 2020 Colorado?
The exact center bore is 66.9 mm. Any wheel or spacer you buy should match this closely, or utilize a centering ring to bridge the gap.
