2012 Chevrolet Volt Wheel Interchange

2012 Chevrolet Volt Wheel Fitment Guide - wheelinterchange.com

Known OEM Fitment For 2012 Chevrolet Volt

The specs below reflect factory equipment for the 2012 Chevrolet Volt. If any value varies by trim or region, confirm with your door-jamb label, owner manual, or the on-page calculator plus OEM sources before purchasing.

Notes:

• Wheels must be hub-centric to 70.3 mm on the Volt or use quality hub-centric rings if the wheel bore is larger.
• Keep the 5x115 bolt pattern. Do not force-fit 5x114.3 wheels.
• Match lug nut thread M12x1.5 and the seat style specified by the wheel manufacturer.

How To Use The Wheel Interchange Calculator

The calculator on this page compares “Wheels from (donor vehicle)” vs “Installed on (your vehicle).” It projects geometry changes so you can spot clearance issues before you buy.

• Step 1 - Baseline: In “Installed on,” select 2012 Chevrolet Volt or enter the OEM specs above.
• Step 2 - Donor wheel: In “Wheels from,” pick the vehicle you are considering as a donor, or manually input that wheel’s size and offset.
• Step 3 - Custom wheel size: Adjust rim diameter, rim width, and offset. The app shows inner clearance to the strut and outer poke relative to the fender.
• Step 4 - Custom tire size: Enter section width and aspect ratio. When you change rim diameter, the tool updates tire diameter in the comparison so you can keep overall diameter close to stock.
• Step 5 - Review results: Aim to keep overall tire diameter within about ±3 percent of stock, maintain adequate inner clearance, and avoid excessive outer poke.
• Step 6 - Verify with OEM data: Cross-check final choices with the Volt service information and physical measurements on your car, especially brake and suspension clearances.

Fitment Checklist Before You Buy

• Bolt pattern: 5x115 only.
• Center bore: Wheel bore must be 70.3 mm or larger. Use hub-centric rings if larger. Do not use if smaller.
• Thread size: M12x1.5 hardware only. Match lug seat type to the wheel design.
• Offset and width: Use the calculator to compare to the OEM 17x7 ET38. Verify inner clearance to strut/spring and outer fender clearance at full lock and compression.
• Brake clearance: Confirm spoke and barrel clearance over calipers and rotor hat. Test fit when possible.
• Tire overall diameter: Keep close to stock to protect ABS, stability control, gearing, and speedometer accuracy.
• Load rating: Wheel and tire load index must meet or exceed OEM.
• TPMS: Use compatible sensors and follow OEM relearn procedures.
• Condition check: If using take-off wheels, inspect for cracks, bends, and corrosion on the hub bore and lug seats.

Plus Sizing And Common Upgrades

The factory baseline is 17x7 ET38 with 215/55R17. Many owners explore mild plus-sizing for appearance or tire selection. These are examples to evaluate in the calculator - not guaranteed fitments. Always validate on your vehicle.

• Same wheel size, wider tire: Consider evaluating a 225-section tire on a 7.0 in wheel. Check fender and inner clearance at full lock.
• Wider wheel, similar diameter: For example, test 17x7.5 or 17x8 with an offset that preserves inner clearance. Use the tool to compare inner clearance and outer poke to OEM.
• Larger diameter wheel: If exploring 18 inch options, select a tire with a lower aspect ratio in the calculator to keep overall diameter close to stock. Confirm ride quality and clearance.
• Winter downsizing: Some choose narrower winter tires for traction. Keep overall diameter near stock and ensure brake clearance with any smaller-diameter wheels.

If the calculator shows significant inner interference, consider a wheel with less positive offset. If poke becomes excessive, choose a more positive offset. Small changes in offset have a large effect - verify carefully.

Installation Tips

• Clean mounting surfaces: Remove rust and debris from the hub face. Lightly brush the wheel mounting pad.
• Hub-centric check: If the wheel bore is larger than 70.3 mm, install quality hub-centric rings that fit both the hub and wheel precisely.
• Hardware: Use the correct M12x1.5 lug nuts/bolts with the seat style required by the wheel. Do not mix seat types.
• Tightening: Hand start all lugs, then tighten in a star pattern. Use a calibrated torque wrench to the OEM specification from your service manual.
• TPMS: Install compatible sensors and perform the relearn procedure per Chevrolet instructions.
• Road test and re-torque: After 50 to 100 miles, re-check torque and inspect for any rubbing under steering lock and over bumps.
• Alignment: Any significant change in wheel width, offset, or tire size should be followed by an alignment check.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• M12x1.5 lug nuts - correct seat style for your wheels
• Hub-centric rings 70.3 mm to your wheel bore
• Tire pressure gauge

FAQs

• What is the bolt pattern for the 2012 Chevrolet Volt?

  5x115.

• What center bore do I need for aftermarket wheels?

  70.3 mm hub bore on the car. Wheels can be larger if you use hub-centric rings to reduce to 70.3 mm.

• What is the stock wheel and tire size?

  Wheel 17x7 ET38 with a backspacing of 5.0 in. Tire 215/55R17.

• Can I use 5x114.3 wheels on a 5x115 car?

  Not recommended. The mismatch can stress studs and compromise safety. Use the correct 5x115 pattern.

• What lug nuts should I use?

  Thread size M12x1.5. Match the seat style to the wheel design as specified by the wheel manufacturer.

• Will different offsets affect rubbing?

  Yes. Less positive offset moves the wheel outward and can cause fender poke. More positive offset moves inward and can reduce strut clearance. Use the calculator to compare to ET38 and check clearances.

• Do I need new TPMS sensors?

  If your new wheels do not include compatible sensors, you will need to transfer or install compatible TPMS and perform the OEM relearn procedure.

• What torque should I use on the lug nuts?

  Refer to the Chevrolet service manual for the exact torque specification for your wheels and hardware. Always tighten with a torque wrench in a star pattern.

• How close should the new tire diameter be to stock?

  Aim to keep overall diameter within about ±3 percent of stock to maintain proper ABS, traction control, and speedometer behavior.

• Will 18 inch wheels fit?

  They may, but it depends on width, offset, and tire selection. Use the calculator to model an 18 inch setup that keeps overall diameter near stock, then verify brake and fender clearances on your car.
