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%.
Size
Diameter of the wheel rim. Each car has its own recommendations for the wheels size it is usually indicated in the documentation. In addition, this parameter must match the tyres inner diameter used if the wheels are purchased separately. The most popular sizes are
15",
16",
17", for SUVs and powerful sports cars —
18",
19" and
20". Don't forget about small
14", and giants
21",
22" and more.
Offset
Departure is the distance from the plane passing through the place where the wheel is attached to the hub, to the plane passing through the middle of the landing width. Positive overhang values mean that the hub is on the outside of the middle of the disc,
negative values mean that the hub is recessed "deep" into the wheel. For each car model, there is an individual departure value that is optimal for stability and controllability.
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.
Big lip
Usually big lip is large enough to place an object on it.
Rims with big lip make the wheels visually wider, which is typical for powerful sports cars or classics.
