2020 Chevrolet Traverse Wheel Interchange

2020 Chevrolet Traverse Wheel Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2020 Chevrolet Traverse

The values below reflect known factory specifications for at least one 2020 Traverse configuration. Other trims or option packages may differ. Always confirm your exact specs on your driver door jamb tire label, owner’s manual, and the Wheel Interchange calculator before ordering.

Approximate overall tire diameter for 255/65R18 is about 31.1 inches. Use this as your baseline when comparing plus sizes in the calculator.

How To Use The Wheel Interchange Calculator

Our calculator lets you compare a potential donor wheel and tire setup against your 2020 Traverse to visualize clearance, poke, and speedometer change.

• Set Installed on your vehicle to 2020 Chevrolet Traverse, then verify the baseline tire and wheel numbers match your door placard.
• Pick Wheels from donor vehicle if you are comparing a takeoff set. If you are planning aftermarket, use Custom wheel size and Custom tire size.
• Adjust rim diameter, width, and offset. When you change rim diameter, the calculator updates the tire diameter in the comparison so you can maintain a similar overall diameter.
• Review inner clearance and outer poke. Offset changes move the wheel roughly 1 mm for every 1 mm of offset change. Wider wheels split the added width to the inside and outside based on offset.
• As a general guideline, try to keep overall tire diameter within about 3 percent of stock for proper ABS, transmission shifting, and speedometer behavior.
• Aim to maintain adequate inner clearance to struts, liners, and control arms. Many installers target 10 mm or more of static inner clearance to allow for deflection. Check brake caliper and spoke clearance too.
• Use the results to plan tire sizes that preserve load index and speed rating at least equal to OEM.

Fitment Checklist Before You Buy

• Bolt pattern must match 6x120. Wheels with 6x114.3 or 6x139.7 are not compatible.
• Center bore is 66.9 mm. If the wheel bore is larger, use quality hub centric rings with 66.9 mm inner diameter. If smaller, the wheel will not fit.
• Offset and backspacing need to clear brakes and suspension while keeping the tire inside fenders. Use the calculator to compare against ET 50 mm and 5.72 in backspacing.
• Rim size. Many 2020 Traverses use 18x7.5. Other trims may differ. Confirm your stock size and ensure brake clearance if downsizing or upsizing.
• Tire size. Keep overall diameter close to stock. Verify load index and speed rating meet or exceed the door placard.
• Load rating. Wheel load and tire load index must be suitable for a 3-row SUV. Do not downrate from OEM.
• TPMS. Plan to transfer sensors or install compatible sensors and perform relearn per GM procedure.
• Lug hardware. Thread size is M14 x 1.5. Match seat type to the wheel design. Do not reuse damaged nuts or bolts.
• Test fit on the front and rear before mounting tires to check caliper, spoke, and hub contact, and to verify the wheel seats fully on the hub.

Plus Sizing And Common Upgrades

Plus sizing can sharpen handling or alter the stance, but it must be done within safe limits.

• Baseline reference. 255/65R18 is about 31.1 inches in diameter. Use the calculator to select sizes that stay close to this diameter.
• Example concept. A size like 255/55R20 has a similar overall diameter on many SUVs. Use the calculator to confirm clearance and diameter for your Traverse, and check your door placard or GM build info to see if your trim offered 20 inch wheels from the factory.
• Wider tires. If you increase section width, you may need a slightly lower offset to avoid inner rubbing, but too low can cause outer fender poke. Let the calculator show inner and outer changes and measure your vehicle clearances.
• Winter downsizing. If considering a smaller wheel with a taller tire for winter, verify brake caliper clearance and maintain overall diameter.
• Ride, load, and towing. Do not reduce tire load index or speed rating. Larger wheels with shorter sidewalls can ride firmer and be more impact sensitive.

Installation Tips

• Preparation. Park on level ground, chock wheels, and use properly rated jack stands. Loosen lug nuts slightly before lifting.
• Hub mating surfaces. Wire-brush rust from the hub face and wheel mounting pad. Surfaces must be flat and clean.
• Hub centric rings. If required, ensure rings are fully seated on the hub and in the wheel. Do not stack rings.
• Lug hardware. Hand-start M14 x 1.5 lugs to avoid cross-threading. Match seat type to the wheel. Do not lubricate lug seats or studs unless the manufacturer explicitly instructs it.
• Torque. Tighten in a star pattern in stages to the factory torque specification for your exact trim. If you do not know the spec, check the owner’s manual or a GM service manual.
• Re-torque. Re-check torque after 50 to 100 miles and after any temperature swings.
• TPMS. Transfer your sensors or install compatible sensors and perform the GM relearn procedure as required.

FAQs

• What is the bolt pattern on the 2020 Chevrolet Traverse?

  6x120. Any wheel you install must match this pattern.

• What center bore do I need and do I need hub rings?

  The Traverse hub is 66.9 mm. If your wheel’s center bore is larger, use hub centric rings with a 66.9 mm inner diameter. If the wheel bore is smaller than 66.9 mm, it will not fit.

• Will wheels from a vehicle with 6x139.7 or 6x114.3 fit?

  No. Those are different bolt circles. Only 6x120 fits.

• What offset should I use?

  The known OEM offset is ET 50 mm for an 18x7.5 wheel on at least one trim. Other trims may vary. Use the calculator to compare any new offset to ET 50 mm and verify inner and outer clearances on your vehicle.

• What is the largest tire I can run without rubbing?

  It varies by trim, suspension, and wheel offset. Use the calculator to keep overall diameter near stock and check inner and outer clearance. Measure on your vehicle and test fit before mounting tires.

• Can I move from 18 inch to 20 inch wheels?

  Possibly, if overall tire diameter, offset, load rating, and brake clearance are correct. Use the calculator to model a 20 inch setup and compare to stock, then verify against your door placard and OEM information.

• What lug nuts do I need?

  Thread size is M14 x 1.5. Match the seat type to the wheel design. Do not mix seat types and do not reuse damaged hardware.

• Do I need new TPMS sensors?

  You can transfer your existing sensors to new wheels if they are compatible, or install new compatible sensors. A relearn procedure is typically required after installation.

• How do I verify my exact OEM specs?

  Check the driver door jamb tire label, your owner’s manual, and your GM build sheet or OEM parts catalog. Use those values as your Installed on baseline in the calculator.
