Example Wheel Size: 16×7 4-100 40S

16 Wheel Diameter

The size of the hankook tyres as measured between opposite edges, across its center.

7 Wheel Width

The width of the wheel as measured across its barrel from the front rim to the rear rim.

4-100 Bolt Pattern

The bolt pattern indicates the arrangement of lug holes and consists of two elements: the number of bolts, or lugs (4 in this case), and the distance between them across the center of the wheel (100mm in our example). For more detailed information, visit our Bolt Pattern page.

40 Offset

The offset of a wheel is what locates the tire and wheel assembly in relation to the suspension. More specifically, it is the measured distance between the hub mounting surface and the centerline of the rim. Our Info Center has more information in the Wheel Offset page.

S Finish

With hundreds of different wheels, there are dozens of different wheel finishes. They are clearly marked at the end of the wheel size (ex. S = silver).
