Tyres with directional tread pattern

Tyres with directional tread pattern have been developed to roll in one direction only. An arrow on the tyre sidewall indicates the direction of rotation on tyres with directional tread. The direction of rotation must be adhered to. This guarantees optimum grip and helps to avoid aquaplaning, excessive noise and wear.

If, however, the tyre is fitted in the opposite direction to the tread pattern, you must take more care when driving as the tyre is now no longer being used according to its designation. This is particularly important on wet roads. The tyres must be replaced as quickly as possible or be fitted with the tread in the correct direction.

Tyre load

The load capacity index indicates how many kilograms can be loaded onto an individual tyre (tyre load).

91 615 kg 93 650 kg 95 690 kg 97 730 kg 99 775 kg

Speed index

The speed index indicates the maximum permitted speed that may be driven when particular wheels are fitted.

P max. 150 km/h (93 mph) Q max. 160 km/h (99 mph) R max. 170 km/h (106 mph) S max. 180 km/h (112 mph) T max. 190 km/h (118 mph) U max. 200 km/h (124 mph) H max. 210 km/h (130 mph) V max. 240 km/h (149 mph) Z over 240 km/h (149 mph) W max. 270 km/h (168 mph) Y max. 300 km/h (186 mph)

Some tyre manufacturers use the code ZR for tyres with a highest permitted speed of over 240 km/h (149 mph).

a) The TIN is the tyre serial number.
