2019 Chevrolet Traverse Wheel Fitment and Interchange Guide
Known OEM Fitment For 2019 Chevrolet Traverse
The following specifications are known OEM data points for the 2019 Chevrolet Traverse. Some trims and option packages may differ. If a value is not shown for your exact trim, verify it on your driver door placard, in the owner manual, or by using the on-page calculator together with OEM sources.

Notes:
The presence of both an 18 x 7.5 in wheel spec and a 255/55R20 tire spec indicates multiple OEM wheel and tire packages were available on the 2019 Traverse. Your trim may differ.
Confirm your exact wheel and tire package by VIN, the tire information placard on the driver door jamb, or your owner manual. If you have a different OEM size, use the calculator to compare it against alternatives before purchasing.
How To Use The Wheel Interchange Calculator
The calculator on wheelinterchange.com lets you compare a potential donor wheel or a custom wheel and tire against your 2019 Chevrolet Traverse to visualize changes before you buy.
Select Installed on your vehicle as 2019 Chevrolet Traverse.
To check a donor setup, pick the donor in Wheels from or enter the donor wheel specs if known.
To test aftermarket options, enable Custom wheel size and enter rim diameter, rim width, and offset. Then enable Custom tire size to enter section width and aspect ratio.
When you change rim diameter, the calculator updates the tire comparison so you can track overall tire diameter and position changes.
Use the results to evaluate clearance and position changes relative to your OEM setup. If your OEM size varies by trim, start by entering the exact sizes from your door placard as the baseline.
Fitment Checklist Before You Buy
Bolt pattern must be 6x120 mm.
Center bore vehicle hub is 66.9 mm. Aftermarket wheels usually have a larger bore and require hub centric rings with 66.9 mm inner diameter. Do not use a wheel with a smaller bore.
Thread size lug nuts or bolts must be M14 x 1.5 and the seat style must match the wheel seat design. Do not mix seat types.
Offset and width verify inner clearance to struts, springs, and brake lines, and outer position relative to the fender. Use the calculator to preview changes.
Brake caliper clearance many wheel designs differ even with the same size. Test fit at least one front and one rear wheel before mounting tires.
Overall tire diameter try to keep overall diameter close to stock to minimize speedometer error and avoid interference. If your OEM size differs by trim, use your exact size as the baseline in the calculator.
Load rating wheels and tires must meet or exceed the Traverse axle and vehicle load ratings.
TPMS plan to transfer, rebuild, or replace sensors compatible with your Traverse. Relearn may be required.
Spare tire and chain clearance verify compatibility if you drive in snow or carry a compact spare.
Plus Sizing And Common Upgrades
Many owners consider plus sizing for appearance and handling. Because the 2019 Traverse had multiple OEM packages, establish your exact OEM baseline first using your door placard.
Plus sizing concept increase rim diameter and reduce tire aspect ratio to keep overall diameter close to stock.
Use the calculator to keep overall tire diameter within a small variance from stock to help maintain speedometer accuracy and clearance.
Monitor offset changes wider wheels often need offset adjustments. Too low an offset can cause fender poke; too high can cause inner rubbing.
Brake clearance larger diameter wheels can improve caliper clearance, but spoke design still matters.
Ride and noise lower aspect ratio tires can sharpen handling but may increase impact harshness and road noise.
Installation Tips
Test fit wheels on the vehicle before mounting tires. Check rotation by hand, turn lock to lock, and compress the suspension if possible.
Clean hub faces and wheel mounting pads. Remove rust and debris so wheels seat flush and true.
Use hub centric rings if the wheel bore is larger than 66.9 mm. The ring ID must be 66.9 mm and the OD must match your wheel bore.
Install the correct lug nuts for M14 x 1.5 studs with the seat style that matches the wheel. Hand start all fasteners.
Tighten in a star pattern in stages to the torque specified in your owner manual. Recheck torque after 50 to 100 miles.
After installation, verify TPMS operation and perform a relearn if required by the vehicle.
Schedule an alignment if you changed wheel width, offset, or tire size.
What is the bolt pattern for the 2019 Chevrolet Traverse
6x120 mm.
What is the center bore
66.9 mm. Use hub centric rings if your new wheel has a larger bore. Do not use a wheel with a smaller bore.
What lug nuts does it use
M14 x 1.5 thread. Match the lug seat type to the wheel design. Consult your wheel manufacturer if unsure.
My door placard shows a different tire size than 255/55R20. Is that normal
Yes. The 2019 Traverse was available with multiple OEM wheel and tire packages. Use your door placard or owner manual as the baseline and compare alternatives in the calculator.
How far can I deviate from the OEM offset
There is no single value that fits every wheel and tire. Use the calculator to preview inner and outer position changes and then physically test fit to confirm brake and fender clearance.
Do I need hub centric rings
Only if the new wheel center bore is larger than 66.9 mm. Choose rings with 66.9 mm inner diameter and an outer diameter matching the wheel bore.
Will changing tire size affect my speedometer
Yes if overall diameter changes. Keep overall diameter close to your OEM size and verify using the calculator.
What torque should I use on the lug nuts
Follow the torque specification in your owner manual or an OEM service source for the 2019 Traverse. Retorque after 50 to 100 miles.
Methodology and sources
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
Bolt pattern / PCD
Center bore direction (donor wheel bore must not be smaller than the hub)
Wheel diameter, width, and offset against known OEM ranges
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
