Designations of tires Example:
195 — tire width in mm
/70 — height relation to width (height of cross section of the tire makes 70% of width) If hotel data on width relation to height are absent (for example, 155 R 13), means it is 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 rim size in inches
89 — the parameter of the bearing ability

If between data 14 and 89 there is a designation M + S, it is about tires with a winter profile. |
N — designation of admissible maximum speed. The letter of speed stands behind the tire size. Symbols of speed belong both to summer, and to winter tires.
