Alloy wheels are expensive. Therefore, some car owners, for various reasons (for example, saving money, etc.), are considering options for purchasing already used "casting". In order not to regret the choice made later, some important points should be taken into account.
It is necessary
- - newspaper with ads;
- - a computer with Internet access.
Instructions
Step 1
First of all, check the data on the appropriate alloy wheel size for your car. This information is usually found in the vehicle's owner's manual, on a sticker in the glove compartment, or on the inside of the fuel filler flap. Then decide where you will buy the product you want. There are many different options: in the car market, car services, according to an advertisement on the Internet or in a newspaper, with friends, acquaintances, etc. Weigh the pros and cons of different ways of acquiring.
Step 2
Please note that it is not enough to choose only the design and the desired size, it is necessary to pay attention to the more important parameters. For example, the fit size of the disc fastener to the hub (diameter of the central hole, the number of holes for taper bolts, the distance between them, etc.), as well as the displacement of the disc surface adjacent to the hub (wheel overhang). Although the last parameter allows deviations of a few millimeters, this can lead to undesirable consequences: a decrease in overhang creates an additional load on the suspension and hub bearings, and its increase can damage the brake assembly.
Step 3
Examine the selected drives carefully. After all, they can have defects that will adversely affect driving safety and the driving performance of the car. Therefore, alloy wheels must not show any visible damage. Also, lightly hit them with an iron object. If the sound is ringing, there are no microcracks imperceptible to the eye. Damaged - emit a dull sound. Scratches are permissible on the surface of an alloy wheel, which do not affect the performance properties and can be removed by grinding.
Step 4
Contact the nearest auto repair shop or service station and check the general condition of the selected instances on the balancing machine. This way you can check the deviations from parallelism, eccentricity of the gadfly and the landing plane, etc. Ask the technician to assess the metal fatigue, as the number of kilometers traveled will affect the condition of the disc in the future.
