How do I know what lug nuts I have?
Knowing the type and size of your lug nuts is essential for maintaining your vehicle's wheels and tires. Lug nuts secure the wheels to the vehicle's hubs, and using the wrong size or type can be dangerous. Here's how you can determine what lug nuts you have on your car or truck.
Inspect Your Lug Nuts
The first step is to visually inspect your lug nuts. Look closely at the size, shape, and threading of the lug nuts on each wheel. Some key things to note:
- Lug Nut Size: Lug nuts come in a variety of sizes, typically ranging from 1/2 inch to 1 inch in diameter. The most common sizes are 12mm, 14mm, and 17mm.
- Lug Nut Shape: Lug nuts can be either conical (tapered) or spherical (ball-shaped) in design.
- Lug Nut Threading: The threading on lug nuts can be either right-hand or left-hand threaded.
Take note of any distinguishing features or markings on the lug nuts, as this can help you identify the specific type.
Check Your Owner's Manual
Your vehicle's owner's manual is another great resource for determining your lug nut specifications. The manual will typically list the correct lug nut size, shape, and threading for your make, model, and year of vehicle.
Measure the Lug Nuts
If you're still unsure, you can measure the lug nuts directly. Use a caliper or micrometer to measure the diameter of the lug nut. This will give you the exact size you need to purchase replacement lug nuts.
Consult a Tire or Auto Parts Store
Finally, you can also take your vehicle to a tire shop or auto parts store and have them identify the lug nuts for you. The staff there should be able to quickly determine the correct size and type based on a visual inspection.
Knowing the right lug nuts for your vehicle is important for safety and proper wheel installation. By following these steps, you can easily identify the lug nuts you have and ensure you get the correct replacements when needed.

Even Lug Number: Measure from the center of one lug to the center of the opposite lug. When shopping for a wheel, you'll see a number like this: 8 x 6.5. This means you have 8 lugs with a 6.5-inch measurement. This same pattern could also be expressed as 8 x 165mm.
How do I find my wheel nut key code?
You'll find your locking wheel nut key's code in the plastic container it originally came in. Usually, this will be stored under the boot floor near your car's spare wheel or tyre inflation kit, though it may instead be somewhere else like the glove box.
What is the most common lug nut pattern?

What do I do if I lost my lug nut key?
If you know who made your wheel locks, your best bet is to contact the manufacturer and order a replacement key.

How do you check lug nuts?
An ideal way is to use a torque wrench, which shows (or can be set) a number that indicates how tight the nut is. Any mechanical shop has them. A roadside way (or driveway) is just to use the tire iron that came with your car and put them as tight as you can.
Can you drive with a missing lug nut?
What would happen if I was missing a lug nut? A car with a missing lug nut is "okay" to drive for a bit, but it will become dangerous. If you lost a lug nut, extra pressure is being put on the remaining lug nuts, causing them to wear out faster. If this happens, you may also notice a wobbly ride.
