2019 Chevrolet Camaro Wheel Fitment Guide
Known OEM Fitment For 2019 Chevrolet Camaro
The figures below reflect a known OEM setup for the 2019 Camaro. Trim packages and brake options can change these values. Always verify your exact trim against the door-jamb tire placard, the owner’s manual, and OEM part numbers before purchasing wheels or tires.
| Bolt pattern | 5x120 |
| Center bore | 67.1 mm |
| Thread size | M14 x 1.5 |
| Rim diameter | 18 in |
| Rim width | 8.5 in |
| Wheel offset (ET) | 32 mm |
| Backspacing | 5.51 in |
| Tire size | 245/50R18 |
Note on offset vs backspacing: the listed offset and backspacing appear inconsistent for an 18x8.5 wheel. Use the calculator on this page to recompute backspacing from rim width and offset, and confirm against OEM documentation for your specific wheel part number.
How To Use The Wheel Interchange Calculator
The calculator lets you compare a donor wheel and tire to what will be installed on your Camaro. It helps you visualize changes in clearance, poke, and overall tire diameter so you can avoid rubbing and speedometer error.
Basic steps:
- Select Wheels from (donor vehicle). Enter the donor wheel and tire sizes, or pick a vehicle if you know it.
- Select Installed on (your vehicle) and choose 2019 Chevrolet Camaro.
- Set Custom wheel size. Adjust rim diameter, width, and offset. The tool will update inner clearance and outer poke compared to your baseline.
- Set Custom tire size. Change section width and aspect ratio to maintain overall diameter. When you change rim diameter, the calculator updates overall tire diameter in the comparison so you can keep it near stock.
- Review results. Aim to keep speedometer error minimal, maintain adequate inner clearance to struts and brake components, and avoid excessive outer poke past the fender.
For trims that differ from the listed baseline, enter the exact OEM sizes from your door placard as the starting point, then compare your desired setup.
Fitment Checklist Before You Buy
Work through these points to reduce the chance of rubbing, vibration, or TPMS warnings.
- Confirm bolt pattern is 5x120 and that the wheel uses the correct lug seat style for your lug nuts.
- Center bore is 67.1 mm. If aftermarket wheels have a larger bore, plan for hub-centric rings sized 67.1 mm to the wheel’s bore.
- Thread size is M14 x 1.5. Use compatible lug nuts with the correct seat type and length for the wheel.
- Offset and backspacing must clear front and rear brakes, struts, and fenders. Use the calculator to compare inner clearance and outer poke against your verified OEM setup.
- Tire outside diameter should stay close to stock to avoid speedometer error and clearance issues. Use the calculator to keep changes small.
- Load index and speed rating must meet or exceed the factory specifications on your door placard.
- TPMS compatibility. Reuse your sensors or fit compatible sensors, then perform the relearn procedure specified by GM.
- Brake caliper clearance. Check spoke design and barrel clearance. Test fit when possible and rotate the wheel by hand to confirm no contact at the tightest points.
- Suspension and body clearance. At full steering lock and full compression, verify clearance to liners, tabs, and fender lips.
Plus Sizing And Common Upgrades
Many Camaro trims were offered with different wheel diameters from the factory. If you are moving up in diameter, keep overall tire diameter near stock by adjusting tire aspect ratio with the calculator. Monitor inner clearance at the front strut and outer fender poke as width and offset change. Larger brakes on some trims require specific barrel clearance, so always verify against your actual brake package. When in doubt, measure your current setup, enter it as the baseline, and compare your target wheel and tire to visualize changes inboard and outboard.
Installation Tips
Prepare the car on level ground and secure it safely. Break lug nuts loose slightly before lifting. Use the correct jacking points and support the vehicle with stands. Clean the hub face and the wheel mounting pad so they are free of rust and debris. If you use hub-centric rings, seat them fully on the wheel. Hand start all lug nuts to avoid cross-threading. Snug in a star pattern, lower the vehicle, then torque in a star pattern to the specification in your owner’s manual for your exact trim and wheel type. Recheck torque after 50 to 100 miles. If you installed different tires or moved sensors, complete the GM TPMS relearn procedure as specified by the manufacturer.
Tools And Helpful Supplies
FAQs
What is the bolt pattern on the 2019 Camaro
5x120.
What center bore do I need
67.1 mm. If your aftermarket wheel bore is larger, use hub-centric rings sized 67.1 mm to the wheel’s bore.
What lug nut thread size does it use
M14 x 1.5. Match lug seat type to the wheel design and do not mix conical, ball, or mag seats.
Will 19 inch or 20 inch wheels fit my 2019 Camaro
Some trims were offered with different diameters, but exact fitment depends on your brakes, suspension, and offsets. Use your OEM sizes from the door placard as the baseline in the calculator, then compare the target size to confirm clearance and tire diameter. Verify with OEM documentation for your trim before buying.
How close should offset be to stock
Start from your verified OEM offset for your exact wheel. Small changes can impact inner clearance and outer poke. Use the calculator to compare measurements and test fit when possible. Prioritize brake and strut clearance and avoid excessive poke beyond the fender.
Why do my backspacing and offset numbers not agree
Backspacing depends on rim width and offset. If a listing shows values that do not line up, use the calculator to recompute backspacing from width and offset and verify against OEM sources for your specific wheel part number.
Can I reuse my factory lug nuts on aftermarket wheels
Only if the seat type and dimensions match the aftermarket wheel. If the wheel requires a different seat or shank, purchase the correct hardware in M14 x 1.5.
Do I need to perform a TPMS relearn after changing wheels or rotating sensors
Many GM vehicles require a relearn after sensor changes or rotation. Follow the 2019 Camaro owner’s manual procedure, which may involve a TPMS tool.
