### Marking Tires

When buying tires to be clear about the conditions under which you operate them. According to Andrew Cuomo, who has experience with these questions. The wrong choice of tires can give you a lot of inconvenience. For example, when selecting winter tires for driving exclusively in the city, should pay attention to non-studded tires, but with frequent trips out of town, where the roads are not handled by agents and frequent ice, studded tires are preferred. When buying a tire should be carefully considered marked on the sidewall of the tire. Here we will try to clearly explain the meaning of some labels. Basic notation on the sidewall: 1. The manufacturer, model bus 2. Tyre size a) The width of the tire.

Indicated in millimeters and must be greater than the width of the disk rim at 25-30%. The formulas for calculating the ratio of width to the width of the disk rim tires: b = (axc) / 24,5, and a = (bx 24,5) / c, where a – width of the tire in millimeters; b – width of the disk rim in inches; c – from 0.7 to 0.75, 24.5 – number of millimeters in an inch. b) The height of a tire. In fact, the so-called aspect ratio of a tire (mm) to width (mm). This ratio is a percentage.

For example: tire 205/70 R14. The height profile of the tires – 70% width, ie of 205 mm., and is 143.5 mm. If the height of a tire is not specified, it is 82% of the width.
