OEM wheel and tire fitment specs for the 2013 Chevrolet Corvette, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
2013 Chevrolet Corvette Fitment Specs
Baseline mounting dimensions used for interchange decisions.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.
Wheels That Interchange With a 2013 Chevrolet Corvette
Results are evaluated from bolt pattern, center bore direction, OEM width/offset envelope, and lug hardware – not bolt pattern alone.
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.

Important notes:
Some 2013 Corvette trims may use staggered wheel setups with different rear sizes. If your placard or manual lists different sizes front to rear, use those as your baseline in the calculator.
If any of your specs are missing or differ from the table, rely on your vehicle’s placard and OEM sources. Do not assume fitment across trims.
How To Use The Wheel Interchange Calculator
The calculator compares Wheels from the donor vehicle against Installed on your vehicle. It also lets you try a Custom wheel size and Custom tire size. Follow these steps:
Enter your 2013 Corvette in the Installed on side. Confirm the baseline size with your door placard or manual.
Enter a donor vehicle or a custom wheel on the other side. Adjust rim diameter, width, and offset. If you change rim diameter, the tool updates tire diameter in the comparison.
Observe the clearance changes for inner suspension and outer fender. Watch for increased poke or reduced inner clearance.
Use the tire size fields to keep overall tire diameter close to OEM to protect speedometer accuracy and ABS behavior.
Record the predicted inner clearance, outer position, and strut or caliper clearance. Use this to pre-check fit before buying.
Fitment Checklist Before You Buy
Verify bolt pattern 5x120.70 and center bore 70.3 mm. If the new wheel’s center bore is larger than 70.3, plan for hub-centric rings. If smaller, it will not seat.
Match thread size M12 x 1.5 and lug seat type required by the wheel. Do not reuse mismatched lug nuts.
Offset and width: Use the calculator to compare your stock 18x8.5 ET56 setup to the new wheel. Confirm inner clearance to suspension and outer fender coverage.
Brake caliper clearance: Physically measure spoke-to-caliper clearance where possible. Paper or clay templates can help if provided by wheel makers.
Tire overall diameter: Keep close to OEM to maintain speedometer and stability system behavior. The calculator shows diameter changes as you adjust sizes.
Backspacing: Compare against the known 6.45 in reference when changing width and offset. Large changes can cause rubbing or strut contact.
TPMS: Plan for sensor transfer or compatible replacements. Relearn procedures may be required after installation.
Load rating: Wheels and tires must meet or exceed vehicle axle loads. Check manufacturer data sheets.
Plus Sizing And Common Upgrades
The 2013 Corvette may be equipped with staggered sizes on some trims. If you plan to plus-size:
Increase rim diameter gradually and select tire aspect ratios that keep overall tire diameter close to stock. Use the calculator to visualize changes.
Wider wheels add grip but can reduce inner clearance. Compare inner position versus stock and verify fender clearance on compression and steering lock.
A small reduction in offset pushes the wheel outward. A small increase pulls it inward. Use the tool to quantify these changes before purchase.
For track or aggressive setups, confirm clearance at full steering lock and over bumps. Inspect the liner, fender lip, and brake lines.
If your trim uses different front and rear sizes, maintain the stagger to preserve handling balance unless a square setup is validated by measurements.
Installation Tips
Test fit each wheel without the tire first when possible. Spin the hub to check caliper and suspension clearance.
Clean hub faces and wheel mounting pads. Remove corrosion to prevent runout and vibration.
Use hub-centric rings if the wheel bore is larger than 70.3 mm so the wheel centers on the hub.
Install lug nuts by hand first to avoid cross-threading M12 x 1.5 studs. Tighten in a star pattern.
Torque to the OEM specification from the owner’s manual or service information. Re-torque after 50 to 100 miles.
Perform a TPMS relearn if sensors were moved or replaced. Follow GM procedures for your model year.
Road test and check for rubbing on turns and over bumps. Inspect inner liners and fender lips after the first drive.
The known bolt pattern is 5x120.70. Verify on your vehicle placard or OEM documentation if your trim differs.
Do I need hub-centric rings?
If your new wheel’s center bore is larger than 70.3 mm, use rings to reduce it to 70.3 mm. If the bore is smaller than 70.3 mm, the wheel will not fit.
What offset should I use with aftermarket wheels?
The known OEM reference here is ET 56 on an 18x8.5 wheel. Use the calculator to compare any new width and offset to this baseline and confirm inner and outer clearances. Always verify against your trim’s OEM specs.
Can I run staggered wheels?
Some 2013 Corvette trims use staggered setups. Check your door placard or manual. If staggered is listed, keep that configuration or validate any change with the calculator and physical clearance checks.
Will changing tire size affect my speedometer?
Yes. Changing overall tire diameter affects indicated speed. The calculator shows diameter differences so you can select sizes that stay close to OEM.
What is the thread size for lug nuts?
M12 x 1.5. Match the lug seat type to your wheels and torque to the OEM specification from service information.
How do I check for rubbing before buying?
Use the calculator to compare inner and outer positions versus stock, then measure your current clearances to struts, liners, and fender lips. Account for suspension compression and steering angle.
Do I need new TPMS sensors?
You can often transfer sensors if compatible with the new wheels. If replacing, use GM-compatible sensors and perform the relearn procedure after installation.
Reminder: If any fitment value is unknown for your exact trim, confirm it using the on-page calculator starting from your door placard specs, and cross-check with OEM manuals or a GM parts catalog before ordering.
