What is the wheel fitment?A wheel’s “fitment” refers to how the wheel will fit within a wheel well or underneath fenders. It’s important to make sure the wheel and tire package you’re purchasing both look good and allows your vehicle to handle properly. There are several things to consider in terms of wheel fitment:
- Bolt pattern
- Diameter and Width
- Positive Offset
- Negative Offset
- Zero Offset
Bolt patternBolt pattern is discussed in detail here, but to summarize, the bolt pattern describes the number of lugs (and lug holes) on the wheel as well as the diameter between those lugs. Bolt pattern is written as an expression that looks like 5×5.5 inches or 4×100 millimeters.
Diameter and WidthThe dimensions or size of a wheel, are described by its diameter (18, 20, 22) and width. (10, 12). 20×10 and 22×12 are common aftermarket wheel sizes, for example. the appropriate size of your wheel is the second thing to keep in mind when it comes to fitment

Offsetwheel offset indicates how the wheel sits in relation to a vehicle’s suspension and body components. The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. There are three types of offset: zero, positive, negative
Positive offsetWhen a wheel has a positive offset the hub mounting surface is toward the front- or wheel side- of the wheel.
Negative offsetWhen a wheel has a negative offset, the hub mounting surface is toward the back or brake side of the wheel’s centerline.
Zero offsetWhen a wheel has zero offset the hub mounting surface is even with the centerline of the wheel.
