2020 Chevrolet Colorado Wheel Interchange

2020 Chevrolet Colorado Wheel Fitment Guide

Known OEM Fitment For 2020 Chevrolet Colorado

The specs below reflect data provided for at least one 2020 Colorado configuration. Other trims and packages may use different wheels and tires. If a value is not listed for your exact trim, confirm it on your tire placard (driver door jamb), in the owner’s manual, or by using the on-page calculator to compare options. Do not assume different trims share the same wheels, brakes, or clearances.

Notes:

• Multiple OEM sizes exist across 2020 Colorado trims. The 17x8 ET33 listing and the 265/70R16 tire listing likely reflect different trims. Verify your truck’s factory size on the door placard or with the VIN and RPO codes.
• Backspacing is sometimes published using different reference points, which can cause small numerical differences. Always measure the actual wheel if clearance is tight.
• The center bore 66.9 mm is critical for hub-centric fit when using OEM wheels. Aftermarket wheels with a larger bore require appropriate hub-centric rings.

How To Use The Wheel Interchange Calculator

The calculator lets you compare a donor wheel/tire to your 2020 Colorado and see changes in inner/outer clearance, poke, scrub, and tire diameter.

• Set Installed on (your vehicle) to 2020 Chevrolet Colorado. If your exact OEM size is different than the table above, input your placard size first so the baseline is accurate.
• In Wheels from (donor vehicle), choose the vehicle you want to borrow wheels from, or enter the wheel’s specs directly.
• Use Custom wheel size to change rim diameter, width, and offset. The tool updates inner clearance to the strut/upper control arm and outer poke toward the fender.
• Use Custom tire size to adjust section width and aspect ratio. Changing rim diameter also updates overall tire diameter so you can keep speedometer error in check.
• Check Results: Keep tire diameter variance small to avoid ABS/TC issues. Watch inner clearance around knuckle, UCA, sway bar, and frame at full lock and bump. Ensure outer poke does not contact the fender or liner.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 6x120. Adapters change geometry and may reduce thread engagement; avoid unless necessary and properly engineered.
• Center bore: OEM is 66.9 mm. If the wheel bore is larger, plan hub-centric rings to 66.9 mm. Never force a smaller bore onto the hub.
• Thread size: M14x1.5. Use correct-seat lug nuts/bolts to match wheel seat type (typically conical for many aftermarket wheels). Verify adequate thread engagement equal to at least the stud diameter.
• Offset and backspacing: Use the calculator to confirm inner clearance to suspension/brakes and outer clearance to fenders. Small offset changes can make large clearance differences.
• Brake package: Trims with larger brakes may require specific spoke profiles and diameters for caliper clearance. Test fit before mounting tires.
• Tire diameter: Keep total diameter changes modest to maintain speedometer accuracy, gearing, and ABS/TC behavior. The calculator shows variance and fender/liner risks.
• Load rating: Wheels and tires must meet or exceed the truck’s GAWR and intended load/towing use. Check wheel manufacturer load specs.
• TPMS: Ensure sensor compatibility and re-learn procedure for the 2020 Colorado.

Plus Sizing And Common Upgrades

Many owners consider moving between 16, 17, and 18 inch wheel options with proportional tire sidewalls to keep overall diameter similar. Because the 2020 Colorado was offered with different factory packages, your safe range depends on brake size, suspension height, and fender clearance. Use the calculator with your truck’s actual placard size as the baseline, then:

• Increase rim diameter by 1 inch and reduce tire sidewall height so overall tire diameter remains close to stock for minimal speedometer change.
• If adding width or a lower offset for a wider stance, verify inner clearance to the UCA and sway bar at full lock, and outer clearance at compression.
• Off-road tires with aggressive shoulders run wider than nominal; account for real measured section width on the chosen rim width.
• If using aftermarket wheels with larger center bores, add hub-centric rings to 66.9 mm to minimize vibration.

Installation Tips

• Test fit a bare wheel on the front hub to verify center bore seating and caliper clearance before mounting tires.
• Clean the hub face and wheel mounting pad. Remove rust and debris so the wheel sits flush and runs true.
• Hand start all M14x1.5 lugs to avoid cross-threading. Tighten in a star pattern.
• Use a torque wrench to torque to the OEM specification for your trim found in the owner’s manual or service information. Re-torque after 50–100 miles.
• If using hub-centric rings, ensure they fully seat on the hub and in the wheel bore.
• Check full steering lock both directions and compress the suspension (ramps or careful bounce test) to confirm no rubbing under load.
• Perform a TPMS relearn and set pressures to the placard value unless your new tire load index requires a different setting per tire manufacturer guidance.

Tools And Helpful Supplies

• Floor jack and rated jack stands
• Socket set for M14x1.5 lugs and a breaker bar
• Torque wrench: Shop 1/2 inch torque wrenches
• M14x1.5 lug nuts that match your wheel seat: Shop M14x1.5 lug nuts
• Hub-centric rings to 66.9 mm if needed: Shop hub-centric rings
• Tire pressure gauge: Shop tire pressure gauges

FAQs

• Q: What is the bolt pattern for the 2020 Colorado?

  A: 6x120. Any wheel you choose should match 6x120 or use professionally engineered adapters after confirming all clearances and thread engagement.

• Q: My door placard shows a different wheel and tire size than listed here. Which is right?

  A: Follow your truck’s placard and owner’s manual. The specs above apply to at least one configuration, but 2020 Colorado trims vary. Use the calculator with your placard size as the baseline.

• Q: Can I run 18 inch wheels?

  A: Many trims can use 18s, but brake package, offset, and tire size determine clearance. Use the calculator to keep overall diameter near stock and verify caliper/fender clearance. Test fit before mounting tires.

• Q: Do I need hub-centric rings?

  A: If your wheels have a center bore larger than 66.9 mm, use rings sized to your wheel’s bore on the outside and 66.9 mm on the inside so the wheel centers properly on the hub.

• Q: What is the correct lug nut torque?

  A: Refer to the 2020 Colorado owner’s manual or GM service information for your trim. Torque with a calibrated wrench and re-check after 50–100 miles.

• Q: How much offset change is safe?

  A: It depends on width, brakes, and suspension geometry. Use the calculator to model inner clearance to the UCA/strut and outer poke to the fender. Physically test fit to confirm.

• Q: Will 265/70R16 fit my 17 inch wheels?

  A: No. 265/70R16 is for 16 inch rims. If your truck has 17 inch wheels, choose an equivalent diameter tire in a 17 inch size. Use the calculator to find a comparable 17 inch tire that keeps overall diameter similar.

Always verify final fitment with physical measurements and OEM documentation before purchasing. This helps avoid vibration, rubbing, and safety issues.
