How to choose rims for your car. Steel or alloy?
Despite the seeming simplicity, the wheel of a car is a fairly complex site that requires a serious approach to the choice of wheels.

The components of steel wheels are made by stamping from a steel sheet, which are then combined in the finished part by means of welding.
Low production costs and rather high quality – these are the reasons that pressed steel wheels equipped with almost all the cars coming down the Assembly line.
The undeniable advantage of steel wheels is their relatively high strength and the possibility of restoring the original geometrical dimensions even after strong deformation of the flange. With a strong impact on a high curb or the bottom of a deep hole pressed CD of steel are only slightly bent, while the cheap light-alloy wheels will simply crack.
Affordable price forged steel wheels — another argument in favor of stop your choice on them.
At the same time, major disadvantages of steel wheels are the insufficient accuracy of production, creating problems in balancing, and a large mass in comparison with alloy.
Material for alloy wheels in most cases, are the alloys based on aluminum. Titanium and magnesium wheels are rare because it is expensive and capricious in operation. The main use of magnesium and titanium disks – expensive sports cars.
The most inexpensive and quick method of making alloy wheels is a common casting. Alloy wheels are an affordable and not always cope with extreme mechanical loads, simply breaking or cracking from impact. The metal has a granular internal structure, which is characterized by the accumulation of microcracks at constant driving on low quality roads.
Forged wheels made as well as cast, casting method, but under high pressure, considerably more expensive, but also stronger than their cast counterparts, because they have a multi-layered fibrous structure.
Rolled alloy wheels are manufactured by casting with subsequent rolling of the rim and are a cross between cast and forged wheels as strength, and price.
The main advantage of alloy wheels is their light weight compared to pressed steel. Four light-alloy disc with a diameter of 15 inches weighs about 20 kg less than the steel disks of the same size.
This significantly increases the clarity of the control car and its responsiveness to the changing the position of the wheels while driving. The service life of the chassis, especially the suspension, increases considerably and the riding becomes more comfortable.
And large openings between the spokes of alloy wheels are more efficient cooling of the brake mechanisms of the machine.
When choosing wheels, be sure to stick to the standard sizes and characteristics recommended by the vehicle manufacturer. What they mean, is explained in detail in the publication "How to decode symbols wheels".Regardless of the type or types of wheel disks, may they serve you faithfully, making the drive comfortable and safe!
