Drive options

Alloy wheels are one of the main components that affect the appearance of the car. Made of lightweight aluminum alloys for injection molding technology. Alloy wheels have a very high strength characteristics. Painted with special anti-corrosive paints and varnishes.
But not only that the benefits of light alloys. There are other reasons to buy a light alloy wheels:

• weight loss as a consequence of the wheels and weight reduction improves booster, reduces the load on the engine and transmission, reduces fuel consumption, improves running smoothness;
• the use of light-alloy wheels improves the cooling of the brake unit, due to its high thermal conductivity of the alloy, and better airflow through the application design;
• technology of production of cast wheels ensure high precision, which minimizes the imbalance, and hence the balance can be made more precise;
• multi-layer coating ensures protection of the wheel from the external environment.

All drives have a standard labeling parameters.

Compliance drive vehicle is determined by the following main parameters:

A - rim size (measured in inches) - the diameter of the circular rim, upon which the tire.

B - landing rim width (measured in inches) - the distance between the inner surfaces of the board contour wheels. Identifies possible tire section width of the installed
The width of a tire - a parameter directly related to the width of the rim of the landing - has a significant impact on the economy, dynamics, maximum speed, handling, braking distance. Wider wheel has a larger contact patch and, consequently, a better link with the road, but we have more rolling resistance and the flow of oncoming air. The result: the dynamics of acceleration worsens, improves manageability.

ET (departure) - the distance from the plane of the wheel adjacent to the hub, to a plane passing through the middle of the landing rim width (measured in millimeters). For each vehicle manufacturer provides a list of valid options for the wheels. Sometimes as a "positive" and "negative-negative", the latter is mostly found in SUVs. Departure is not constant and, depending on the design features of the disk can vary by up to 10 mm for the same car. Most car crash from 30 to 40 mm.

If significant deviations from the recommended tire departure could hurt a wheel arches or suspension components. In addition, installation of wheels flying, much less provided for, resulting in a significant reduction in vehicle stability in cornering, steering sensitivity to road irregularities and uneven braking forces.

DIA - Diameter of the central hole should match (as closely as possible) diameter of the spigot on the hub of the vehicle (measured in millimeters). The deviation of its value in a big way. In this case, the wheel is used to set the transition centering ring (supplied with alloy wheels).
hump - a small circular protrusions on the surface of the disc, made for tubeless tires. In turns they improve the fixation side tires on the drive, thus preventing the wheels of depressurization.

PCD - PCD of fixing holes (measured in millimeters). This value must correspond to the standard, otherwise impossible to achieve a secure fit on the wheel hub. The deviation of 2 mm, even lead to a skewed fastening elements (bolts).

PCD can be calculated by measuring the distance between the centers of distant mounting holes (this can be done without taking the usual line of wheels from the car)

• I drive with the four mounting bolts (or nuts) PCD is the distance between the centers of distant (opposing) bolts or nuts.
• In a five-disc mounting bolts (or nuts) PCD is the distance between the centers of distant (any non-adjacent) bolts or nuts multiplied by a coefficient of 1.051
