Lug Nut Size - M14 x 1.5

Buy Lug Nuts on amazon. When measuring your lug nut sizes, you'll need to pay attention to two separate numbers. The first number indicates the diameter of the stud, and for metric-sized nuts this is measured in millimeters between threads.

Standard lug nuts are denoted by a second number which expresses thread pitch in terms of how many threads per inch there are on that particular nut or bolt. As an example, a 12mmx1.25 sized lug nut will have both 12mm diameter as well as 1.25 mm thread pitch!

The number of lug holes on the wheel should match the number of studs on the hub, and the distance between the holes should be identical. Change your vehicle's bolt pattern by installing wheel adapters to match the lug scheme of the wheels that are to be installed.
