MEASURING A WHEEL BOLT PATTERN

MEASURING A WHEEL BOLT PATTERN


The bolt pattern or bolt circle of a wheel and hub is the diameter of an imaginary circle formed by the center of the wheel lugs. Bolt patterns vary between different car manufatcurers. When purchasing wheels or replacement axles this measurement is very important Most intermediate GM cars will have a 5 on 4-3/4" bolt pattern. This means there are 5 wheel studs and the bolt pattern is 4-3/4". To determine the bolt pattern a measurement must be made from one stud to another stud farthest away on the axle or wheel. This measurement is not equal to the actual bolt pattern measurement, but it can be used to determine bolt pattern.

Actual Measurement C/L Studs
Bolt Pattern
4-5/16"
= 5 on 4-1/2"
4-1/2"
= 5 on 4-3/4"
4-3/4"
= 5 on 5"

So, your Chevy 5 on 4-3/4" wheel or axle actually measures 4-1/2" between wheel stud . C/L - (Center Line)
