Truck Speed

Haian recommends that the maximum truck speed is 50km/h.And excessive speed will produce abnormally high temperature in tyres. Therere 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 tyreston-mile-per-hour(TKPH)rating.
