2. Incorrect selection of wheels and tires can adversely affect handling, wheel and bearing life, brake cooling, speedometer/odometer accuracy, braking distance, headlight direction, bumper height, ground clearance, and tire-to-body clearance.
Depending on the type of tires, the following disks are installed, indicated in the table "Correspondence of tire sizes with wheel disk parameters". As an example, possible markings are given:
6.5JJx15H5 ET50 PCD114.3 DIA60
In the wheel disk marking, the first digit "6,5"denote the rim width (H), expressed in either millimeters or inches. The letters "JJ" indicate the shape of the rim. The subsequent number "15"indicates the wheel rim seat diameter (D) in inches, which must match the seat diameter of the tire being installed. The number "39" after the letters ET stands for the disk offset (ET) in millimeters. The following symbols are also found in the marking: "H5" means the presence of five holes for mounting bolts or studs, numbers after the designation "DIA" - diameter of the central hole, "PCD" - the diameter of the holes for the mounting bolts or studs.
