Wheel Guidelines

JaxQuickfit Wheels Guidelines

JAX Tyres also offers a range of great value wheel and tyre packages.

Wheels and the Law Measuring Offset and PCD

Each state has certain legal requirements, when wheels outside the manufacturers recommended range are fitted to a vehicle.

These requirements mainly relate to wheel rim widths, the fitting of nuts and studs and the increase of track measurement.

Modifications outside the legal guidelines are not permitted and the correct matching of wheels and tyre is vital to ensure the continued safe operation of the vehicle. See your JAX Tyres wheel specialist for the best advice on all performance and safety aspects.

Wheel Care and Maintenance

For lasting care of your alloy wheels it is recommended you clean them regularly with soap and water. Check first before using automotive detergents, as they may corrode the alloy metal. Re-tension your wheel nuts or studs with a wheel brace on a regular basis.


Please make sure that you check with your insurance company to ensure that your choice of wheels is compatible with your car.

Measuring Offset and PCD

There are two ways of measuring offset. Centre line offset is the distance from the centre line of the wheel to the face of the wheel mounting surface. Back space offset is the distance from the extreme back edge of the rim to the wheel mounting surface. Pitch Circle Diameter (PCD) is the diameter of the bolt circle.
