Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs.
Bolt patterns can be 4-, 5-, 6-, or 8-lug holes. A bolt circle of 4x100 would indicate a 4-lug pattern on a
circle with a diameter of 100mm.
The diagram (upper, left) indicates the proper measuring methods. 6-lug wheels are measured like

Note: When measuring a 5-lug wheel the measurement is only an estimate unless accurately measured
using a bolt pattern gauge. A bolt pattern gauge is a specialty tool and is not widely available. To ensure
the proper fitment of 5-lug wheels, Tire Rack's fitment specialists have the exact bolt pattern information for
all vehicles and review the information before listing a wheel as an exact fit for that vehicle in search results.
When selecting wheels by vehicle, only wheels that will be a proper fit for the vehicle selected are shown.
