How to Measure Wheel Bolt Pattern

Tired of your stock wheels and looking to make a change? Whether you’re upsizing or just picking a style you like better, one measurement you’ll have to know is your bolt pattern. Sometimes you can find it listed online but if you’re ordering custom wheels that can’t be returned you want to make sure this information is correct – and there’s no better way than measuring it yourself.

A wheel’s bolt pattern is made up of two numbers – the first indicates how many bolt holes are on the wheel and the other is the diameter of an imaginary circle formed by the centers of the wheel lugs. A bolt pattern of 5×115 would mean the wheel has five bolt holes spaced out evenly on a 115mm diameter circle.

EVEN Number of Lugs (4, 6, or 8 Bolt)

Measure center to center of two holes directly across from each other.

Measure from the back of one hole to the center of the third hole. This is the most common way to estimate a 5-lug bolt circle. You can also measure from the center of one hole to the center of the third hole using 1.05 multiplier to find your bolt circle. For an accurate measurement, you’ll need to use a bolt pattern gauge.
