TEMPERATURE LIMIT. HIGH SPEED REDUCES TYRE LIFE

TEMPERATURGRENZE. SCHNELLZUGTEMPO ZEHRT AN DER REIFENLEBENSDAUER

THE CRITICAL TEMPERATURE OF TYRES IS IN THE REGION OF 95 DEG CELSIUS. WHEN THIS LIMIT IS EXCEEDED, WHICH IS POSSIBLE AT A SPEED OF 100 KM PER HOUR, THE TYRE LIFE SUFFERS AND SAFETY IS REDUCED. FROM THIS IT CAN ALSO BE SEEN THAT LORRY DRIVERS SHOULD NOT EXCEED 100 KM PER HOUR EVEN WHEN IT IS POSSIBLE TO CHECK THEIR TYRE PRESSURES REGULARLY AND TO CONVINCE THEMSELVES USING THE TYRE DEPRESSION VALUE WHETHER THE STATIC DEPRESSION EXCEEDS 12 TO 15 PERCENT. THIS PERCENTAGE IS REGARDED BY TYRE MANUFACTURERS AS THE LIMIT FOR SAFETY AND IS FOR EXAMPLE 33 TO 38 MM FOR TYRES OF SIZE 11.00 RZO, ACCORDING TO THE MAKE. THE ROLLING RESISTANCE OF THE TREAD ALSO HAS AN INFLUENCE ON THE TYRE TEMPERATURE. IT INCREASES WITHIN THE REGION MEASURED LINEARLY WITH THE SPEED AND REACHES CONSIDERABLY DIFFERENT VALUES DEPENDING ON THE CONSTRUCTION AND CONDITION OF THE RUNNING SURFACE. FINALLY THE ROLLING RESISTANCE OF THE TYRE ALSO AFFECTS FUEL CONSUMPTION.
