Understanding the Wheel Size
Example Wheel Size: 16x7 4-100 40S
16
Wheel Diameter: The size of the wheel as measured 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.

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).
