How to choose alloy wheels

Alloy wheels are currently very popular. among motorists. Excellent manufacturing accuracy and balancing, low dead weight, high reliability and a huge variety of styles and designs – these and many others characteristics have contributed to seeing “casting” instead stamped iron discs can be both on expensive foreign cars, and on the old “basins”. All that a car enthusiast wants tune your car – choose the right parameters drives under your car.

We recommend reading an article from an expert on choosing the best brake pads and the secrets of choosing brake discs.

The best manufacturers of alloy wheels for cars

Traditionally, the best are legendary manufacturers in the field of car tuning and motorsport, whose names are already widely known to everyone not one dozen years:

  1. Alpina

  2. Brabus

  3. Vossen

  4. Aez

  5. Rondell

  6. Dezent

  7. Borbet

  8. Volk

The catalogs of each of the above brands include many models for every taste and suitable for installation on any car. When choosing beautiful wheels, you should not pay attention only for technical specifications, but also for operational features highlighted using specific models by people on their iron horses. Finding them is not difficult – just register on the appropriate thematic auto forums and social networks.

Types of alloy wheels

Modern alloy wheels are made of high strength aluminum alloys and are balanced on the most accurate optical equipment, resulting in perfect evenness and lack of heartbeat while riding. By the principle of manufacturing all discs can be divided into two conditional groups.

Classic alloy wheels

Classic alloy wheels

They are made of special aluminum alloys by casting. into the mold under pressure, as a result of which it is ensured uniform structure, correct geometry and balancing. Processed on special equipment for breeding balancing almost to level zero and are covered special polymer compounds to give aesthetic appearance.

Advantages

  • A variety of styles and designs;

  • Perfectly balanced;

  • Simplicity of operation and unpretentiousness in leaving;

  • High strength;

  • Size from 13 to 25 inches;

disadvantages

  • Soft aluminum is easily damaged due to contact with hard surfaces and after falling into a hole;

  • Top models of the road;

  • Prone to cracking;

Forged alloy wheels

Forged alloy wheels

The principle of manufacturing “forging” is similar to the above, but after the surface of the disc is processed by a special tool, due to which their mechanical strength and and total weight decreases. Widely used in motorsport and among professional tuners for whom the weight of the disc does not play at all lower value than stylish design.

Advantages

  • Great appearance;

  • Perfectly balanced;

  • Durable and resistant to abrasion;

  • A variety of colors and designs;

  • Light weight;

disadvantages

  • Fragile, can crack when hit in a deep hole;

  • Expensive;

The main criteria for choosing alloy wheels

selection criteria for alloy wheels

Choosing a “cast” for a particular car always means a decision many serious compliance issues specific drive parameters to those declared by the factory – machine manufacturer. Pay attention to the following the nuances.

Cast disc diameter

It has the most direct effect on the total value. wheels and the ability to install it on a specific car. IN wheels with a diameter of 13 to 23-24 inches are for sale.

The most “popular” are considered sizes from 14 to 17 inches – it is these drives that are mostly installed on modern domestic cars and foreign cars. The larger the diameter of the cast disc – the prettier it looks and the tougher its chassis becomes when operating on poor roads.

The minimum and maximum diameter should be completely comply with the parameters provided by the manufacturer a car. Exceeding the recommended diameter means that the disc when the wheel is eversed, it will cling to the wing liner and rub against the arch, the installation of a smaller disk is very often impossible – the brake caliper abuts against the disc.

Razboltovka

Parameter that displays the number and size of bolts with which this or that disk is fixed to the car. This parameter determined by the manufacturer of the machine, the drive is selected for number and diameter of mounting holes on the hub. For instance, a traditional BMW 5×120 bolt pattern means that for wheel fasteners are used five bolts with a length of 120 millimeters.

Diameter of central hub hole

Denotes the size of the central hole in the hub car designed to fix the cast disk. Often the values ​​encountered are 71.5, 72.8, 74.2 millimeters.

You should choose alloy wheels, the diameter of the central heating of which corresponds to the hub of the car and the parameter that is defined by the manufacturer.

In the case when the disks do not match the central heating parameter, for their installation will require the use of a special spacer that changes this parameter. Spacer is a special transition cylinder with variable diameter – in one part diameter CO of the disk, in the other – CO of the hub;

Disc out

The parameter indicating how far the edge of the disk is from its landing plane. The value is denoted by the letters ET and is measured in millimeters. The higher the value, the farther the center will be removed. the disk from its edge and the deeper the wheel will “sit” in the arch. TO for example, on the same car wheels with ET20 take off will stick out from the arch more than those, with the departure of ET47. This parameter is selectable. solely on the basis of specific recommendations automaker.

Disk width

The wider the disc, the larger the contact patch of the tire with the expensive and the its functional features are better. Negative factor -increase ruts: the car begins to behave too “nervously” on rough road. On sale represented as single-wide cast disks in which the width of the four wheels is identical, and wide, whose width is different for the front and rear axles. The latter are usually intended for sports cars and provide improved handling and dynamics of the car.

Disc weight

A significant parameter for participants in various auto races. Higher wheel weight – the higher the unsprung mass of the car and the worse dynamics for acceleration and braking. It is for this reason that race drivers try to use light forged wheels, “shoeing” them in special racing tires. Overclocking by similar manipulations the dynamics decreases by 0.4-0.5 seconds in the discipline of 0-100 kilometers in hour.
