What’s the Torque Spec for Lug Nuts?

Most passenger cars fall between 75 and 100 ft-lbs. SUVs and crossovers run roughly 80–120 ft-lbs, and full-size trucks typically need 100–150 ft-lbs (up to 165 ft-lbs on some heavy-duty dual-rear-wheel trucks). These are reference ranges, not a substitute for your vehicle’s actual spec — always confirm against your owner’s manual before torquing.

Torque by Thread Size, When You Don’t Know Your Vehicle’s Spec

Thread SizeTypical ApplicationTorque Range (ft-lbs)
M10 × 1.25Small cars (Miata, older Japanese)65–76
M12 × 1.25Japanese cars (Nissan, Subaru)72–87
M12 × 1.5Most passenger cars70–100
M14 × 1.5Trucks, large SUVs, European cars85–120
M14 × 2.0Heavy-duty trucks120–165
7/16″-20Older domestic vehicles55–65
1/2″-20Domestic cars, light trucks75–100
9/16″-18Full-size trucks, vans135–145

This table is a general starting point compiled from published references, not a factory spec for any specific vehicle. Measure your thread size and cross-check against your manual — don’t torque to a table value alone on anything safety-critical.

How to Find Your Actual Spec

  1. Owner’s manual — the definitive source, usually in the maintenance or tire-change section.
  2. Driver’s door jamb sticker — some manufacturers list lug torque next to tire pressure info.
  3. Wheel manufacturer’s documentation — aftermarket wheels can call for a different torque than OEM.
  4. The chart above — only when nothing vehicle-specific is available.

How to Torque Lug Nuts Correctly

  1. Clean the hardware. Dirt, rust, or debris on the studs, nuts, or mounting surface affects torque readings and prevents a solid seat.
  2. Hand-start every nut. Thread each one by hand first to confirm it isn’t cross-threaded — cross-threading a stud is expensive to fix.
  3. Snug in a star pattern, not sequentially around the wheel, so it seats evenly against the hub.
  4. Torque in stages — roughly 50%, then 75%, then 100% of final torque, following the same star pattern each pass. Don’t go straight to full torque on the first pass.
  5. Re-torque after 50–100 miles. New wheels and tires settle; check every nut again after that break-in distance.

Star pattern reference:

  • 4-lug: X pattern (1-3-2-4)
  • 5-lug: star (1-3-5-2-4)
  • 6-lug: opposite pairs (1-4-2-5-3-6)
  • 8-lug: star across the bolt circle

Common Mistakes

  • Finishing with an impact gun. Impact tools deliver inconsistent torque and routinely exceed spec — use them for initial snugging only, and always finish with a calibrated torque wrench.
  • Lubricating the threads. Don’t apply oil, grease, or anti-seize unless the manufacturer specifically calls for it. Lubrication cuts friction enough that a wrench reading 100 ft-lbs could be applying 130+ ft-lbs of actual clamping force — enough to stretch studs or warp rotors.
  • Skipping the re-torque. New wheels, new tires, and tire rotations all call for a recheck after 50–100 miles.
  • Using the wrong lug nut style. Conical (tapered), spherical (ball-seat), flat-seat, and mag-seat nuts aren’t interchangeable — the wrong style won’t center the wheel properly.

Steel Wheels vs. Alloy Wheels

In most cases the torque spec doesn’t change with wheel material — it’s set by stud size, thread pitch, and hub design, not by whether the wheel is steel or alloy. Exceptions exist: some manufacturers specify different torque for steel vs. aluminum wheels, aftermarket wheels may use a different seat type (conical vs. flat) requiring different nuts, and magnesium wheels are more sensitive to over-torquing and can crack. When in doubt, check the wheel manufacturer’s documentation rather than assuming.

A Note for Off-Road, UTV, and ATV Wheels

The torque data above is compiled from passenger car and truck references — it does not cover UTV, ATV, or other off-road-specific wheel hardware, which commonly use different stud sizes and torque values than the automotive tables above. If you’re torquing wheels on a UTV, ATV, or similar off-road platform, don’t extrapolate from this chart — check the vehicle manufacturer’s spec directly.
