TYRE SIZE MARKINGS

The tyre size designation is usually, for example, 195/70 R 14 84 T and means the following:

1. Manufacturer name (brand)

2. Tyre model name.

3. Tyre size marking

4. Speed ​​marking 

5. Construction type 

6. Load class (LI) 

7. Maximum load capacity (1 LBS; 0.454 kg) 

8. Maximum load pressure (1 PSI; 6.9 kPa) 

9. Fabric material + (number of layers on the side and tread) - ply rating

10/11. Tubeless Inner ring

12. Radial ring in occurring cases

13.  Reinforced (reinforced tire / load capacity greater than 4 LI)  

14. Special mark (eg E-approval number)  

15. DOT mark (Department of Transportation). Indicates the time of manufacture of the tire in four digits. The first 2 issues indicate the week of manufacture of the tires and the next 2 years of manufacture. 

16. UTQG (Uniform Tire Quality Grading)     

17. The tire usually has either an OUTSIDE marking on the outward side or an arrow pattern indicating the direction of rotation of the tire.

The most common tyre speed classes:

F = 80 km/h = 50mph
J = 100 km/h = 63mph
L = 120 km/h = 75mph
M = 130 km/h = 81mph
N = 140 km/h = 87mph
P = 150 km/h = 94mph
Q = 160 km/h = 100mph
R = 170 km/h = 106mph

S = 180 km/h = 112mph
T = 190 km/h = 118mph
U = 200 km/h = 125mph
H = 210 km/h = 131mph
V = 240 km/h = 150mph
Z = more than 240 km/h = 150+mph
W = 270 km/h = 168mph
Y = 300 km/h = 187mph

Maximum Tyre Load - Load Index

The Load Index (LI) indicates the maximum permissible load capacity of the tyre. In a normal passenger car, the load capacity of the tyre must be at least a quarter of the total weight of the car. If the axle masses are marked separately on the registration certificate, the capacity must be at least half of the axle mass.

6- and 8-bolt ones are modified in the same way as 4-bolt ones.

ET = Offset = Distance from the rim mounting flange to the rim centreline in millimeters.
Positive offset: The mounting flange is outer than the rim centreline, as shown in the picture.

Offset 0: The mounting flange is aligned with the centre line of the rim, as shown in the picture.

Negative offset: The mounting flange is inner than the rim centreline, as shown in the picture.
