195 - tire width in mm
/70 - ratio of height to width (tire cross-sectional height is 70% of the width).
If there is no special indication of the ratio of transverse dimensions (e.g. 155 R 13), then we are talking about the normal ratio of height and width, which for radial tires is 82%.
R - radial design (radial tire)
14 is the rim diameter in inches.
89 - characteristic of the permissible load. Attention: If the designation M + S is between the numbers 14 and 89, then we are talking about a tire with a winter tread pattern.
H - letter designation of the permissible maximum speed; H: up to 210 km/h.
The letter designation of the speed is given after the designation of the tire size. The speed symbols are valid for both summer and winter tyres.
Letter designation of speed
| Letter designation | Permissible maximum speed, km/h |
| Q | 160 |
| S | 180 |
| T | 190 |
| H | 210 |
| V | 240 |
| W | 270 |
Attention: If the word reinforced is present at the end of the tire designation, then this is a reinforced tire, for example, for Van and Transporter cars.
Tire manufacturing date

- CU - manufacturer's abbreviation
- L2 - tire size
- UM8 - bus version
- 5000 - date of manufacture - 50th week of 2000
