Wheels are basic elements of car wheels. Original design, a wide range of patterns and colours make drivers more likely to opt for alloy rather than steel models. Well-chosen rims will emphasize the character of every car. Additionally, they offer excellent parameters, given in the process of shaping the aluminium alloy.
What are the characteristics of alloy wheels?
The main advantage of alloy rims is the flexibility of aluminium. The material susceptible to processing makes them much more resistant to deformation than steel wheels. What distinguishes alloy wheels is also the effective heat dissipation from the brakes. All thanks to light metal alloys, which are excellent conductors. This has an invaluable effect on maintaining optimum braking power under difficult conditions.
The freedom to design the shoulder system allows for more cool air to be created, thus preventing excessive friction and overheating of individual brake components. Aggressive and sporty design can therefore not only look good but also dramatically improve the performance and durability of discs and calipers. In addition, alloy wheels provide optimum rigidity and are able to significantly reduce car wheel deflection when driving on bends.
Alloy wheels - basic parameters:
- diameter and width - represented in inches (1 inch = 2.54 cm)
- spacing of bolts - a very important parameter, each car has a different spacing
- offset (ET, offset) - defines the distance between the mounting plane of the rim and its vertical centre of symmetry. This value can be positive or negative. ET is zero when the mounting plane is exactly on the vertical axis of symmetry
- centering opening - its diameter is specified in millimetres
There are several most popular types of alloy wheels, such as: five-arm, multi-arm, rims with an edge, spoke, Mesh, twist or concave rims.
