How to Measure Bolt-Patterns

Bolt patterns are simply the measurement of an imaginary circle that lies across the center-line of the lugs. Whether you are looking to adapt or match a new set of wheels, we have a simple guide to help you estimate your bolt circle.

Wheel Bolt Pattern Guide
The easiest way to estimate the 5 lug bolt pattern, is to measure from the back of a hole to the center of the second hole.
For a 4 lug wheel, measure center to center of two holes directly across from each other.
Measuring a 6 bolt wheel requires you to measure center to center of two holes directly across from each other.
To measure an 8 lug bolt pattern, measure center to center of two holes directly across from each other.

No need to guess any longer! Speedway Motors has a precision bolt circle template that simplifies the most common 5 lug patterns for you. Our bolt circle template and our Wheel Bolt Pattern Tool are must have tools for the shop or swap meet.
