Lug Nuts and Bolts
Lug nuts hold your wheel to the vehicle by clamping force, and getting three specifications right is what generates that clamping force correctly: seat type, thread pitch and length.
Seat type is the shape where the nut meets the wheel. Conical or acorn seat is a 60 degree taper and is by far the most common on aftermarket wheels. Ball or radius seat is a rounded seat used by many European manufacturers including VW, Audi and some BMW. Mag or shank seat uses a flat washer face with a long straight shank and is used on many Honda and Toyota factory wheels. Mixing these up is the most common cause of wheels coming loose.
Thread pitch has to match your studs exactly. Common pitches are 12x1.5 on Toyota, Honda and most GM, 12x1.25 on Nissan and Subaru, 14x1.5 on modern Ford, GM trucks and Dodge, and 14x2.0 on older Ford. Length matters because you need enough thread engagement, and the rule of thumb is that the stud should engage at least as many threads as the diameter of the stud.
Torque to the manufacturer specification with a torque wrench, in a star pattern, and re-torque after 50 to 100 miles. Impact guns overtighten and stretch studs.

Lug Nuts and Bolts: the questions people ask
How do I read a tire size?
Metric sizes give section width in millimetres, then aspect ratio as a percentage of that width, then rim diameter in inches. So 275/60R20 is 275mm wide with a sidewall 60 percent of 275mm tall on a 20 inch wheel. Flotation sizes are simpler: 35x12.50R20 is 35 inches tall and 12.5 inches wide on a 20 inch wheel. Every listing here also publishes the overall diameter worked out for you.
Will a bigger size fit without a lift?
Usually one size up over stock clears on a half ton truck with a leveling kit. Going from a 33 inch to a 35 inch tire almost always needs a leveling kit plus trimming at the front bumper corners. 37 inch tires need a real lift and normally a re-gear to get the drivability back.
What do load index and speed rating mean?
Load index is the weight one tire carries at its rated pressure. Speed rating is the sustained speed it is certified for. Never fit a tire with a lower load index than the placard in your driver door jamb calls for. On a truck that tows, going under the placard rating is the commonest cause of a tire failing under load.
Do tires arrive mounted?
Loose tires ship on their own and need a local shop to mount and balance them. Wheel and tire packages ship mounted, balanced and ready to bolt on.
How fast do orders ship?
Orders ship from a United States warehouse, normally within 1 to 3 business days of clearing. Orders over $199 ship free, and below that a flat rate is shown at checkout before you pay. Tracking is emailed as soon as the shipment is created.
What can I return?
Unmounted, uninstalled parts in original packaging can be returned within 30 days. A wheel that has had a tire mounted on it, and a tire that has been fitted, cannot be returned because neither is new any more. That is why we check the fitment data on every order against the vehicle you give us before it ships.
Can someone check fitment for me before I order?
Yes, and it costs nothing. Send us the year, make, model, trim and what is on the vehicle now, and we will tell you what fits, what will rub and what it takes to clear.
