Do you have a classic vehicle but don't see any aftermarket wheel fitments for it on our website? Looking for aftermarket rims that you know we carry, but they aren't listed for your vehicle? We get calls all the time from people who are trying to fit a wheel to their vehicle for which we don't have fitment data. However, you're not out of luck!
You always want to check, before you do anything else, to see if we have wheel fitments for your vehicle - you might be surprised.

Bolt Pattern (Bolt Circle):
You will need to figure out the bolt pattern of your hubs, which may be found online or by measuring.
To measure your bolt pattern, establish an imaginary circle that passes through the middle of each stud and measure the diameter of the circle. For hubs with an even number of studs, simply measure across from the middle of one stud to the middle of its opposite.
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.
You will also need to know the diameter, width, offset and backspace of the wheels. Backspace measures the distance from the mounting plate of the wheel to the back edge of the wheel, where offset measures the distance from the mounting plate of the wheel to the center of the wheel barrel. The higher the backspace, the further back into the fender well it will sit. To help you understand offset and backspacing, take a look at the diagram below:
Centerbore is the machined opening on the back of the wheel that centers the wheel properly on the hub of a vehicle. This hole is machined to exactly match the hub so the wheels are precisely positioned as the lug hardware is torqued down. Keeping the wheel centered on the hub when it is mounted will minimize the chance of a vibration. Certain wheels are vehicle model specific and will come from the factory with a bore machined to match that vehicle. Some wheels are designed to fit several vehicle models and will use a centering ring system to reduce the bore size to match the hubs of different vehicles. These rings keep the wheel precisely positioned as the lug hardware is torqued down.
Some wheels are non-hub centric by design. These are known as lug centric wheels. With these wheels it is critical to torque the lug hardware with the vehicle on jack stands, off the ground. This allows the nuts or bolts to center the wheel and torque down without the weight of the vehicle pushing them off center.
Wheel Weight Capacity:
Just like tires, all wheels have a maximum load. If you have a heavy vehicle like a truck, you may need to try and locate the GAWR (Gross Axle Weight Ratio) and make sure that for each axle, the max load of two wheels will hold the load of the vehicle.
