Thread each nut on by hand for the first few turns so you never drive home a crossed thread. Tighten in a star pattern with a torque wrench set to your vehicle's spec, which you can look up on our torque reference chart. Re-torque after 50 to 100 miles, since fresh hardware can settle as it seats.
Common questions
Do these match my wheel's seat type?
Bulge acorn lug nuts use a tapered conical seat. Conical, mag, and ball seat styles are not interchangeable, so check that your wheel's lug holes are machined for a conical seat before ordering.
How many should I order?
They are priced per piece, so order one nut for every stud. Count the studs on one hub and multiply by the number of wheels you are fitting.
