Alloy wheels: how to select, operate

An important element of each car - wheels, which are divided into types. They affect the appearance, comfort and behavior of the car on the road.

Cast wheels in some ways ahead of other species. The main differences - three, they are as follows:

1. The weight.
2. Cost.
3. Appearance.

Acquired due to the fact that they are manufactured in the original form, and therefore every motorist will find an option to your liking.

How to Choose alloy wheels

Material

Depending on the raw materials for the production are divided into 2 types:

1. Magnesium.
2. Aluminum.

Aluminum models in its composition includes silicon and other components. This creates advantages, among which are:

• cost - aluminum does not apply to precious metals;
• low weight (density of 2.7 g / cm³);
• resistance to corrosion and chemicals. This increases the service life, as the surface oxide film is formed of high strength.

In addition, the aluminum refers to metals with low thermal conductivity. This feature creates a good cooling of the brake system, and therefore improves its performance.

Alternatively, for the production of magnesium is used. The composition and percentage of aluminum present. magnesium advantage - weight, since the density of this material is 1.7 g / cm³.

Compared with aluminum models, they are durable and are not subject to serious damage when running into an obstacle. The other parameters at a high level. The only negative - the susceptibility to corrosion and other aggressive substances.

Partially solve the problem of helping multilayer coatings, but for use in conditions of constant rain and snow they are not suitable.

The advisability of buying aluminum or magnesium disks varies depending on operating conditions. If you need advanced wheel, it is necessary to give preference to models of magnesium. Aluminum is also suitable for everyday use.

cost of

The cost of well-known brands of products is high, but they can boast of quality. On the market there are many replica models, which have an identical appearance.

Cheap wheels lose the originals. The main reason is technology. Cheap versions are made without control. It is not possible to achieve perfect performance, so caught the wheel of irregular shape, balancing them - a serious problem.

Another difference lies in the quality of the materials used. Properties are achieved by combination of aluminum (magnesium) and other components are not disclosed. Cheap replica fragile, as made of aluminum. For this reason, there is a myth about the insufficient strength of the species.

Original products have a good painting, which is characterized by integrity. Covering cheapest options uneven, quickly cracking and flaking.

Life time. With proper care, can serve for decades, and inexpensive products are destroyed in 2-3 years, and they can not be restored. The reliability of the original models supported by the guarantee.

In the case of faults manufacturer will remove them for free. Such a possibility when buying cheap analogues no damage will have to eliminate at their own expense.

Another parameter that affects the running quality - material. Original products of famous brands held strict control on compliance with environmental regulations. Products that are manufactured in China, can not boast of quality, as the main purpose of the manufacturer - to make a cheap copy of the famous brands.

The weight. On average, it is a third less than that of iron. This has a positive effect on controllability and increase the life of the suspension parts. The reason is that the lower the weight of the product, the less the weight of the vehicle.

In order to fit wheels on different cars, they make universal. The central opening has a maximum size. Some motorists faced with a situation where the hub protrusion diameter for landing is 65 mm and the diameter of the opening - 70 mm.

Some manufacturers sell alloy wheels for their vehicles. It is proposed 2 options: complete and partial equipment. A first embodiment involves the acquisition of a set consisting of a wheel hub mounts and protection.

With enough budget you can buy original products with a set of accessories. SPECIAL OFFER hard to find, because the sites are making big cheat.

The partial configuration sold without fasteners and other parts. Nuts and bolts. This will get the original wheel with a set of high-quality accessories at low prices. If necessary, takes the lantern wheel size.

You need to choose a model with a manufacturer's warranty and quality certificateConfirming product specifications. If it is impossible to get it, then do not purchase. The certificate includes a name, a description of properties and so forth. If the seller has such a document, then you can safely choose the goods in his shop.

Pay attention to the selection of fasteners. Bolt molded disk is longer than the steel embodiment. Buying short bolts may cause the loss of the wheel while driving, causing an accident. Nuts are selected of appropriate size. They are securely fastened to the wheel hub. The material should be tough and withstand.

Exploitation

Designed for smooth roads without holes and obstacles. Therefore, careless drivers or beginners is better to give preference to other species.

The usefulness of the winter in question. Road slippery and icy conditions greatly increase the risk of strokes. If you are not confident that you can in all situations to control the car, it is best to put the winter pressed discs.

Some manufacturers produce wheels, coating which breaks down under the influence of road salt and other reagents. This can lead to the fact that in the spring they will lose the form, they will have to rebuild.

It is recommended to use a high winter tires that have a positive effect on controllability and grip. When installed on the vehicle light alloy wheels, the major diameter is chosen in combination with low-profile tires. This choice can not be called successful for driving on poor coverage.

malfunctions

1. Chipped.
2. Cracks.
3. Scratches.
4. Dent.

If a problem is an urgent need to fix it. If you ignore the damage it causes further destruction, and repair is no longer possible. Restore you can own, but good repair will only professionals. The main requirement - maintain the correct geometry, which alone is almost impossible to achieve.

Liquidated damages:

• manual rectification;
• welding;
• welding;
• rolling.

manual straightening - need a hammer and a sledgehammer. It is necessary to properly assess the strength and number of strokes, or condition can only worsen.

Welding used to eliminate major damage. A long time will not be repaired. Most manufacturers do not recommend to expose the wheel to high temperatures, as this would violate the structure and geometry. The main drawback lies in the insecurity, because if the wheel again burst while driving, this will cause an accident.

Popular considered rolling. It is used to remove dents and other non-serious injuries. The cost is low. It does not involve extreme heat.

To completely restore the appearance of the need for painting. When purchasing a used / have options should be carefully inspect the surface. If it spots that it is impossible to clean - this is evidence of exposure to high temperatures.

Quality restoration leaves no trace and correct color of a uniform application of the wheel will return the original appearance.
