The aspect ratio on a tire is the height from the wheel rim to the top of the tread, expressed as a percentage. This information can be found near your car or truck's wheels with an easy-to-read label that will tell you what this number means in terms of driving performance!


R17 - Rim Diameter

When you buy new tires for your car, the first thing that will catch your eye is the rim diameter. This is the distance measured in inches across the face of the wheel, from bead seat to bead seat.

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!

Bolt Pattern - 5x112

The bolt pattern (PCD) is essential for wheel fitment because it determines the compatibility of the aftermarket rims with the car's hub.

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.
