Count the number of lug holes: 5
Measure from the center of one lug hole to the farthest edge of the opposite lug hole
For a 5-lug wheel, use the center-to-center method if possible
If measuring by hand, measure from the back edge of one lug hole to the center of the second hole across from it
Record the measurement in millimeters or inches
Compare the measurement to a bolt pattern chart to identify the pattern
Common 5-lug patterns include 5×4.5, 5×5, 5×112, and 5×114.3
Verify the pattern before buying wheels or adapters
