Lug nut torque chart
General lug nut torque values by wheel stud size and by vehicle class, in pound-feet and newton-meters. Use it as a starting point, then always confirm the exact figure for your vehicle.
By wheel stud size
| Stud size | Torque (lb-ft) | Torque (Nm) |
|---|---|---|
| 10 mm | 45 | 61 |
| 12 mm | 80 | 108 |
| 14 mm | 110 | 149 |
| 7/16 in | 70 | 95 |
| 1/2 in | 80 | 108 |
| 9/16 in | 105 | 142 |
| 5/8 in | 145 | 197 |
By vehicle class (typical)
| Vehicle | Torque (lb-ft) | Torque (Nm) |
|---|---|---|
| Compact car | 80 | 108 |
| Midsize / sedan | 90 | 122 |
| Full-size / SUV | 100 | 136 |
| 1/2-ton truck | 120 | 163 |
| 3/4 & 1-ton truck | 140 | 190 |
These are typical ranges only. Correct lug torque varies by vehicle, wheel material, and stud size, so always use the value in your owner manual or service data. Tighten in a star pattern in stages, and re-check after 50-100 miles on new wheels.
Converting or staging the spec?
To convert between lb-ft and Nm or work out a staged tightening sequence, use the Wheel Torque Calculator or the Bolt Torque Calculator.
Why lug torque matters
Under-torqued lug nuts can loosen and let a wheel wobble or come off; over-torqued nuts stretch studs and warp brake rotors. The right, even torque clamps the wheel securely without damaging the hardware.
How to tighten lug nuts
Snug all nuts by hand, then torque in a star or crisscross pattern in two or three stages up to the final value. Lower the vehicle so the wheel is loaded, do a final pass, and re-check after the first short drive.
FAQ
What is the correct lug nut torque?
It depends on the vehicle and stud size, typically 80-100 lb-ft for cars and 120-140 lb-ft for light trucks. Always confirm with your owner manual.
Should I grease the wheel studs?
Generally no. Most torque specs assume clean, dry threads; oiling them can lead to over-clamping and stud failure unless the manufacturer specifies otherwise.
Do I need to re-torque after fitting?
Yes, especially on new or alloy wheels. Re-check after 50 to 100 miles, as the joint can settle and lose clamp force.
