Rim width
Wheel rim width. This parameter determines the width of the tyre profile that can be used with this disc. When purchasing tyres, it is worth considering separately that the width of the disk should be less than the width of the tyre profile by 25 – 30%.
Bolt pattern diameter
The diameter of the conditional ring along which the mounting holes on the disk are located. Measured at the centers of the holes. This parameter must exactly match the corresponding wheel hub parameter. Together with the number of mounting holes, it forms a bolt pattern (PCD). The most popular values are 4 and 5 bolt discs, with corresponding PCD values:
4x98,
4x100,
4x108,
4x114.3,
5x100,
5x105,
5x108,
5x110,
5x112,
5x114.3,
5x115,
5x120,
5x130. For 6-bolt discs, the most common bolt pattern is
6x139.7.
Centre bore diameter
The diameter of the centre hole must match the diameter of the centering lug on the vehicle hub. It may also be larger; then adapter rings are used to install the wheel.
