Measuring a dual bolt pattern on a wheel involves identifying two sets of bolt holes that allow the wheel to fit multiple vehicles. To measure accurately, you’ll need to determine the number of bolt holes and the diameter of the circle they form.
What is a Dual Bolt Pattern?
A dual bolt pattern refers to wheels designed with two sets of bolt holes. This design allows the wheel to fit various vehicle models, providing flexibility and convenience for car owners and mechanics. For example, a wheel might have a 5×114.3 and a 5×120 bolt pattern, meaning it can fit both specifications.
How to Measure a Dual Bolt Pattern on a Wheel?
Measuring a dual bolt pattern involves a few simple steps:
- Count the Bolt Holes: Identify how many bolt holes are on the wheel. Common patterns include 4, 5, 6, or 8 holes.
- Measure the Bolt Circle Diameter (BCD): For even-numbered holes, measure from the center of one hole to the center of the hole directly opposite. For odd-numbered holes, measure from the center of one hole to the far edge of the hole directly across.
- Repeat for the Second Pattern: If the wheel has a dual pattern, repeat the measurement for the second set of holes.
Why Choose Wheels with Dual Bolt Patterns?
Wheels with dual bolt patterns offer several benefits:
- Versatility: Fit multiple vehicles, making them ideal for people with multiple cars or those who frequently change vehicles.
- Resale Value: Easier to sell since they fit more vehicles.
- Convenience: Simplifies the process of finding replacement wheels.
Practical Example: Measuring a Wheel
Consider a wheel with a dual bolt pattern of 5×114.3 and 5×120:
- 5×114.3: Five bolt holes with a circle diameter of 114.3 mm.
- 5×120: Five bolt holes with a circle diameter of 120 mm.
To measure, use a ruler or a caliper:
- For the 5×114.3 pattern, measure from the center of one bolt hole to the far edge of the opposite hole.
- Repeat the process for the 5×120 pattern.
