Understanding Bolt Patterns
Bolt patterns are an important aspect of a vehicle’s wheels, as they determine the compatibility of a wheel with a particular vehicle. The bolt pattern is the number of bolt holes and the diameter of the circle that passes through the center of each hole. For example, a bolt pattern of 8×6.5 means that there are eight bolt holes, and the diameter of the circle passing through the center of each hole is 6.5 inches.
