If you are looking to set up your car with these type of wheels, you should at least know about different terms for example offset, PDC, centrebore and up-stepping, just before buying and establishing your car with alloy-made wheels. Offset is normally seen engraved about the wheel. It's the distance between your hub mounting face at the wheel's rear and its center line. On the other hand, PDC or Pitch Circle Diameter, estimates the diameter of the circumference drawn within the center of the bolt holes of the wheel. For centrebore, it depicts the size of of the wheel's rear hole into which the hub is fitted. The holes should perfectly match the hub's size so that the wheels can be positioned appropriately. For up-stepping, this more related to the method of improving your wheel's diameters and lessening the profile of your tires.
When fitting your set of alloy-made wheels, you need to ensure first that the bolts perfectly fit the hubs. There are numerous available bolts that mainly rely on their diameter, thread and seating. Usually, the wheel company may be able to guide you in this particular matter. Some companies may even do the fitting for you personally free of charge. Furthermore, you need to assess if you possess the 4 plastic spigot rings that assist in the wheel-hub interface.
When it comes to caring for your alloy-made wheels, you should ensure that regular maintenance and attention is offered. You'll have to rinse the wheels from dirt and grit that may damage the wheel's surface. Preferably, you should wash your wheels regularly with tepid soapy water. Avoid the use of any type of abrasive cleaners and hard cleaning pads like those made of wire-wool. Furthermore, it is ideal that you let your wheels cool off first prior to washing them. Lastly, steer clear of the use of wheel cleaners that you simply see being used in car wash services, as these are not really effective.
