What size are the lug nuts on a Chevy Volt?
The lug nuts on a Chevy Volt use five lugs per wheel, with a thread size of M14 x 1.5 and a conical seat—the recommended wrench size is 19 mm (3/4 in).
Across Volt generations (2011–2019), the wheel hardware is standardized for typical passenger-car wheels. This means five lug nuts, M14 x 1.5 thread, conical seats, and a 19 mm hex head for installation. Torque is commonly around 100 ft-lbs, but always confirm your vehicle’s specific spec in the owner's manual or service information for your year.
Core specifications
The following details summarize essential specs you need when purchasing or servicing Volt wheels.
- Thread size: M14 x 1.5
- Seat type: conical (tapered) seat
- Number of lug nuts per wheel: 5
- Required wrench size (across flats): 19 mm (3/4 in)
- Typical torque specification: about 100 ft-lbs (135 N·m); verify exact value for your year and trim
Knowing these specs helps you source correct hardware and perform safe wheel changes without damaging studs or wheels.
Notes by model year and wheel variants
GM used the same basic lug hardware on Volt models across its production years, but differences can occur with aftermarket wheels or run-flat configurations. Always check your owner's manual or the GM service information for your specific year if you’re replacing lug nuts or installing new wheels.
Maintenance tips for lug nuts
When replacing or reusing lug nuts, consider the following best practices:
- Always use the correct torque spec for your Volt year (typically around 100 ft-lbs).
- Check lug nuts after the first 50–100 miles of driving and re-torque if required.
- Inspect lug nuts for wear, corrosion, or damaged seats; replace as needed.
- Use the appropriate socket size (19 mm) and avoid using impact tools that can over-torque or damage studs; use a torque wrench for final tightening.
Following these maintenance tips helps ensure wheel safety and proper long-term fastener integrity.
Summary
In brief, Chevy Volt lug nuts are M14 x 1.5 with a conical seat, five per wheel, tightened with a 19 mm wrench, and typically torqued to about 100 ft-lbs. Always verify the exact specifications for your specific year and wheel setup in the owner's manual or GM service documentation.
