2. Incorrect wheel and tire selection can adversely affect handling, wheel and bearing life, brake cooling, speedometer/odometer accuracy, braking distance, headlight beam direction, bumper height, ride height, and tire to body clearance.
Depending on the type of tires, the following disks are installed, indicated in the table "Correspondence of tire sizes to wheel disk parameters and tire pressure".
Table. Correspondence of tire sizes to the parameters of wheel disks and tire pressure.
For example, a possible marking is given:
5.5JJx14H2 ET45 4H PCD100 DIA54
In the marking of wheel disks, the first digits "5,5" indicate the width of the rim (H), expressed either in millimeters or inches. Letters "JJ" indicate the shape of the rim. Next number "14" indicates the diameter of the wheel disk (D) in inches, which must correspond to the fit diameter of the tire being installed. Number "45" after the letters ET stands for disc offset (ET) in millimeters.
Also in the labeling there are the following designations: "H" or "H2" means the presence of one or two annular protrusions on the rim, "4H" indicates the number of holes for mounting bolts or studs, the numbers after the designation "DIA" - diameter of the central hole, "PCD" - the diameter of the location of the holes for mounting bolts or studs.
