Alloy wheels made of light metal, usually the alloys based on aluminum or magnesium and are made by casting them in the form.
Alloy wheels, in addition to an attractive exterior design with a number of advantages over conventional steel. First of all, it is their weight - light alloy wheels in order more easily, and thus have a number of technical advantages for the vehicle as a whole. Reducing the mass of the wheel allows you to not only reduce the unsprung weight of parts and reduces the force of inertia, but also to achieve better quality of work throughout the suspension, and therefore manageable.
Alloy wheels on the car, installed in place of steel, make it possible to achieve lower fuel consumption and reduce the force of the steering system needed for management. Reduced inertia significantly improve the dynamic characteristics of the car. Yes, and they do not look at an example of elegant steel, improving the design of automobiles. The only drawback of cast discs as compared with steel is its much lower strength.
Alloy wheels are matched to the same parameters as usual, on the basis of the diameters of the rim and the central hole of the wheel hub, as well as diameter, location and number of holes for fasteners. In addition, choosing alloy wheels, pay attention to the width of the rim and the disk radius.
