Size: is the diameter of the rim in inches (1 inch = 2.54 cm). Possible sizes are predetermined by the car manufacturer. It is not allowed to use smaller rims than provided by the manufacturer.

Rim width: is measured between the rim flanges. The dimension is in inches. When choosing tires, take into account the width of the rim and the car manufacturer's recommendations.

ET, offset: is not a strictly defined parameter, such as spacing. It depends on the width of the rim. ET is given in mm. The smaller the offset, the more the rim is, which increases the wheelbase, positively influencing the car's stability. The service book or ASO provides only the parameters of the currently installed rims.

Center bore: it is the dimension of the rim center hole diameter given in mm. If the car has a smaller hub diameter, centering rings are used. The ring is used to center the rim in relation to the car's hub. After screwing it, no force acts on it. It is a safe solution used by all rim manufacturers.

Color: determines the colors in which the offered item was made. Pictures are taken under natural lighting.

The working shape of the screw head, must correspond to the shape of the mounting hole made in the rim. We distinguish between spherical( spherical), conical or flat sockets for flat rim holes. The standard is a cone with an angle of 60 degrees

TPMS Sensors - the parameter determines whether the TPMS pressure sensors can be used with a given rim.
