The choice of a car drive is quite a responsible matter. After all, not only the quality of the car's movement, but also your own safety will depend on which wheels you buy.
Instructions
Step 1
When choosing discs, please note that they are made from different materials. The least expensive and more common are steel wheels. They are made of sheet metal, and the design includes a rim and a "plate" welded to it. The jammed surface of such a disc is easy to straighten, they are quite durable and technologically advanced. However, keep in mind that steel rims are quite unattractive, which is why some motorists install decorative hubcaps on them. In addition, such discs have low corrosion resistance and a relatively high weight. The advantages of steel discs include strength (they do not crumble or burst upon impact) and a relatively low price.
Step 2
In the cabin, you can have cast aluminum wheels. They are much lighter than steel ones, they are distinguished by a variety of designs and a higher price. Aluminum discs are quite resistant to environmental influences, as an oxide film forms on their surface, which prevents corrosion. However, aluminum wheels also have disadvantages. They practically do not have the ability to elastic deformation. And this leads to a reduction in the service life of low-profile rubber.
Step 3
Please note that split discs may be present in the showroom. When they are made, the cast rim is attached to the spokes with titanium bolts. Such disks weigh more than cast ones, but the process of their manufacture is rather expensive and complicated, therefore, composite disks are used when operating sports cars and executive cars.
Step 4
There are also cast magnesium wheels. They are superior to aluminum in terms of impact strength and their own weight, but they have very low corrosion resistance. For Russian roads, sprinkled with chlorine compounds in winter, such discs are not very suitable, since they quickly become covered with unaesthetic stains.
Step 5
Please note that there are forged wheels that are made from magnesium aluminum alloys, but have a different production technology. In terms of their parameters, they are much superior to steel and alloy wheels, but they have a high price. The advantages of such disks include impact resistance, structural rigidity, and low weight. Forged wheels are practically not subject to corrosion, do not require additional coating, but have a very high price and simplified design.
