2018 Chevrolet Camaro Wheel Interchange

2018 Chevrolet Camaro Wheel Fitment Guide

Known OEM Fitment For 2018 Chevrolet Camaro

The values below reflect an available factory configuration for the 2018 Chevrolet Camaro. Trims and packages can vary. If your Camaro’s equipment differs, use the on-page calculator and confirm against the owner’s manual, the tire placard on the driver door jamb, or a GM parts catalog by VIN.

If your door sticker lists a different tire size or wheel spec, enter your exact values in the calculator to baseline your vehicle before comparing alternatives.

How To Use The Wheel Interchange Calculator

The calculator on wheelinterchange.com lets you compare a potential donor wheel and tire setup against your 2018 Camaro so you can visualize clearance and diameter changes before you buy.

• Set Installed on - choose 2018 Chevrolet Camaro and confirm the baseline values match your door sticker or OEM documentation.
• Set Wheels from - enter the donor wheel specs you are considering. If you only know bolt pattern and size, add those first, then refine offset, center bore, and tire size.
• Custom wheel size - adjust rim diameter, width, and offset to see inner clearance and outer poke changes relative to the Camaro’s reference setup of 18x8.5 ET32.
• Custom tire size - enter section width and aspect ratio. When you change rim diameter, the calculator updates tire diameter in the comparison so you can keep overall diameter close to stock.
• Review results - focus on inner clearance to the strut and liner, outer position vs fender, backspacing, and tire diameter difference. Aim to keep diameter change small to protect speedometer and driver assist behavior.

Use the measurements as a starting point. Always verify brake caliper clearance, hub bore fit, and stud engagement on the vehicle before driving.

Fitment Checklist Before You Buy

• Bolt pattern: The wheel must be 5x120. Do not attempt to fit 5x120.65 or 5x114.3.
• Center bore: The Camaro hub is 67.1 mm. A wheel with a larger bore can be used with 67.1 hub-centric rings. A smaller bore will not seat on the hub.
• Offset and width: Use the calculator to compare against the OEM 18x8.5 ET32. Check inner clearance to suspension and outer fender poke. Backspacing that grows too much can contact struts or liners.
• Thread interface: Threads are M14 x 1.5. Match lug nuts to the wheel’s seat style and material. Do not mix conical and ball seats.
• Stud engagement: As a safety guideline, target engaged thread length about equal to the stud diameter. For M14, that means roughly 14 mm of full thread engagement. If using spacers, ensure longer studs or proper-length hardware.
• Tire diameter: Keep overall diameter close to stock to maintain speedometer and ABS behavior. Many installers aim for within about 3 percent. Use the calculator to see the change.
• Brake clearance: Physically test fit to confirm spoke and barrel clearance over the front calipers and rear brakes.
• TPMS: Plan to transfer your sensors or purchase compatible units, then perform a relearn procedure per the owner’s manual.

Plus Sizing And Common Upgrades

Plus sizing means increasing wheel diameter while adjusting tire aspect ratio to keep overall tire diameter similar. Example calculations only: if you move from an 18 inch wheel to 19 inch, you would typically reduce the tire’s aspect ratio so the sidewall height decreases and the overall diameter stays close. Use the calculator to try sizes like keeping 245 width but changing aspect ratio as wheel diameter increases. Do not assume any larger size will clear your fenders or brakes. Verify offset, width, and diameter changes on the calculator, then test fit.

Wider wheels and tires can improve grip, but small offset changes can push the tire outward or inward more than expected. Evaluate poke and inner clearance for both front and rear. If you consider spacers to fine tune stance, account for the effective offset change and ensure proper hardware and hub-centric location.

Installation Tips

• Clean the hub face and the wheel mounting pad. Remove rust so the wheel seats flush. A thin anti-seize film on the hub pilot can help prevent future sticking. Do not lubricate wheel studs or lug nut seats unless specified by the manufacturer. Torque values are for clean, dry threads.
• Hand start all lug nuts to avoid cross-threading the M14 x 1.5 studs.
• Tighten in a star pattern in stages to center the wheel on the 67.1 mm hub.
• Final torque: Torque specifications can vary by trim and wheel material. Check your owner’s manual or OEM service information for the correct value for your Camaro, then use a calibrated torque wrench.
• Re-torque after 50 to 100 miles of driving.
• If using hub-centric rings, ensure they are seated fully on the hub and in the wheel before torquing.

Tools And Helpful Supplies

• 1/2 inch torque wrench
• Jack stands
• M14 x 1.5 lug nuts that match your wheel’s seat style
• 67.1 mm hub-centric rings for wheels with a larger center bore

FAQs

Do all 5x120 wheels fit my 2018 Camaro?
Not necessarily. You must also match center bore to 67.1 mm or use correct hub-centric rings, verify offset and width on the calculator, and confirm brake clearance and proper stud engagement.

What offset should I use?
The reference setup listed here is 18x8.5 ET32. Changes in offset depend on your target width and brake clearance. Use the calculator to see how inner clearance and outer poke change relative to that baseline, then test fit.

Can I run spacers?
Possibly, but only with hub-centric spacers and appropriate-length hardware that maintains safe M14 x 1.5 thread engagement. Spacers reduce effective offset, so recheck clearance in the calculator and on the car.

Do I need hub-centric rings with aftermarket wheels?
If the wheel’s center bore is larger than 67.1 mm, yes. Rings center the wheel on the hub to minimize vibration. If the bore is smaller than 67.1 mm, the wheel will not fit.

What tire diameter change is acceptable?
Many installers aim to keep overall diameter within about 3 percent of the OEM reference to help maintain speedometer accuracy and electronic system behavior. Use the calculator to quantify the difference for your chosen size.

What lug nut type should I buy?
Match the thread to M14 x 1.5 and the seat style to your wheel design. Many aftermarket wheels use a 60 degree conical seat, but verify with the wheel manufacturer before purchasing.

What is the correct torque for the lug nuts?
Torque can vary by trim and wheel material. Check the owner’s manual, the service manual, or an OEM database for your exact 2018 Camaro configuration, then torque in a star pattern on clean, dry threads.

Will larger brakes affect wheel fit?
Yes. If your Camaro has a performance package or aftermarket big brakes, spoke and barrel clearance can change. Measure or test fit and use the calculator to compare inner barrel clearance before buying wheels.
