Before measuring the wheel pattern, it’s essential to understand the different components involved.
- Bolt Pattern: This refers to the arrangement and spacing of the wheel lugs that attach the wheel to the hub. It is expressed as a number followed by a letter, for example, 5×114.3. The number represents the number of lug holes, and the number after the ‘x’ represents the diameter of the circle formed by the center of the lug holes in millimeters.
- Center Bore: This is the diameter of the central hole in the wheel, which fits over the vehicle’s hub. It’s important to ensure that the center bore of the wheel matches the hub diameter of the vehicle to avoid misalignment or damage to the hub.
- Hub-Centricity: This refers to the way the wheel is centered on the hub. A hub-centric wheel has a center bore that is slightly larger than the hub diameter, and a hub-centric ring is used to ensure the wheel is centered on the hub.
Measuring Bolt Pattern
To measure the bolt pattern, follow these steps:
- Locate two adjacent lug holes on the wheel.
- Place the calipers or measuring tape across the center of the two lug holes.
- Measure the distance between the centers of the two lug holes. This measurement represents the bolt pattern diameter.
- Repeat this process for all adjacent lug holes. Ensure all measurements are consistent.
- The bolt pattern is then expressed as the number of lug holes followed by ‘x’ and the diameter of the circle formed by the center of the lug holes. For example, if the wheel has five lug holes and the diameter is 114.3 mm, the bolt pattern is 5×114.3.
Measuring Center Bore
To measure the center bore, follow these steps:
- Locate the central hole in the wheel.
- Place the calipers or measuring tape across the hole, measuring the diameter.
- This measurement represents the center bore diameter.
Determining Hub-Centricity
Determining hub-centricity involves examining the wheel’s center bore in relation to the vehicle’s hub.
