The wheel bolt pattern on your car, as the name implies, is the number of wheel studs (or threaded holes for wheel bolts) and the distance that the holes are from each other. For instance, a common bolt pattern for older VWs and Hondas is 4x100, which refers to the fact that there are four bolt holes in the wheel and the holes are 100mm across from each other. On a 5x108 bolt pattern there are five lug holes 108mm across from each other. If the bolt pattern of a given wheel does not match the bolt pattern on the car’s hub, the wheel cannot be used on that car. However, you can install an adaptor that changes the wheel lug pattern.

Things you need
- Floor jack
- Jack stand
- Tire iron
- Torque wrench
- Wheel adaptor
Find out if an adaptor is available for the bolt pattern that you want to convert your car to. Not every bolt pattern can be converted to just any alternative bolt pattern. Check out a company that sells wheel adaptors to see if they have what you need. If you cannot find the adaptor you are looking for, you may be able to have the adaptors custom made.
Loosen the wheel lugs that hold your wheels on. With a floor jack, lift the vehicle and lower it onto jack stands. Remove the lug nuts and the wheel and set the wheel out of the way.
Place the wheel adaptor onto the vehicles hub. Install the supplied bolts that came with the adaptor. Tighten the lug nuts to 43.1kg/ft with a torque wrench. Make sure that the wheel studs do not stick out past the adaptor. The hub mounting surface must be completely flat. If the studs protrude past the adaptor, you will have to install shorter studs.
Place the new wheel that you are installing onto the studs on the adaptor. Install and tighten the lug nuts to 43.1kg/ft with a torque wrench. Lower the vehicle of the jack stand and back to the ground with the floor jack.
Tips and warnings
- Installing an adaptor to change your lug bolt pattern will cause your wheels to be located further away from the body and may create interference issues with the bodywork. Also keep in mind that the further away from the suspension the wheel is, the more stress is placed on the hub and the suspension.
