Tires Knowledge
Truck Speed

Haian recommends that the maximum truck speed is 50km/h. And excessive speed will produce abnormally high temperature in tyres. There’re two speed limitations: the actual maximum speed that the vehicle can attain and the average operating speed that the vehicle can sustain. The average operating speed is limited by the tyres’ton-mile-per-hour(TKPH)rating.

Damage Caused by Excessive Speed:


Resulting Damage

Higher heat generation inside tyre

Heat separation
