Designations of tires Example:
195 — width of the tire in mm
/70 — the relation of height to width (the height of cross-section section of the tire makes 70 % from width) If hotel data on the relation of width to height are absent (for example, 155 R 13), means it is a question about "normal"
H — a class of speed, N: to 210 km/h (on new tires it is brought not always).
R — a radial design
14 — the size of a rim in inches
89 — parameter of bearing ability
