The bus tyres are mainly used on city buses, which are characterized by slow driving speed, large passenger capacity, long driving distance and long driving time. This determines that the bus tire has its unique demand point. For example, the bus often stops at the station, and sometimes it cannot avoid rubbing with the road curb. Generally, the bus tire needs to be thickened in the sidewall design to effectively protect the carcass and reduce the damage caused by the tires frequently stopping at the roadside.
