Bolt pattern & hub
Compare wheel and vehicle dimensions, or calculate a bolt circle from a measurement.
Matching these dimensions is only part of fitment. Confirm offset, brake clearance, load rating, fastener type, thread and engagement with the wheel manufacturer.
Measure center-to-center between two adjacent bolt holes. Recheck the result against the wheel’s stamped specifications.
PCD = adjacent-hole distance ÷ sin(180° ÷ bolt count). Rounded measurements can hide differences between close bolt patterns.
