The difference with ordinary tires for the load coefficient and speed index first shows that ordinary tires can also be loaded, but the load index will be lower than the special load tire, the load index will be marked on the tire side wall in order to facilitate consumer identification, the choice of tire load standard to greater than the total mass of the vehicle as a low standard; The total mass will be marked on the vehicle license is the total weight allowed after full load, heavy tires usually have a parameter such as numbers + letters, such as 91V, 105V, 96W, etc., the front number indicates the load index of the tire, and the English letter behind indicates the speed level of the tire. Some tires have two load indices, which respectively mean that the tire can withstand different loads in the case of single and twin tires, the general single load index is high, and the twin load index is slightly lower.
Heavy duty tires usually should pay attention not to overload the use of tires, overload will lead to excessive heat generation of tires, wear and tear, affecting its service life. Overspeed overload is also the main cause of tire blowout, heavy-duty tires using low heat generation formula, speed (heavy load) control within 60km/h of short-haul transportation, tire heat dissipation performance will be better; The thickened sidewall design, the rigidity of the sidewall is stronger, effectively prevent the sidewall rock when the twin tires are installed, and provide better safety protection for the tires; The core tire inlet design provides better bearing performance for the tire. The safety performance and bearing performance of the specification series tires are excellent, the tread wear is smooth, and there is no abnormal phenomenon such as tread block. According to the comprehensive data analysis of tire use, the safety performance, load-bearing performance and comprehensive performance of the tire are improved by about 20% compared with similar products.
Heavy-duty tire This series of tires uses the special formula for the mine, the speed (heavy load) is controlled below 40km/h for short-distance transportation, and the tire has better anti-puncture performance and anti-collapse block performance, effectively extending the service life of the tire on the harsh road surface such as the mine; The thickened tire side design, the rigidity of the tire side is stronger, effectively prevent the tire side clamping stone when the twin tires are installed, and provide better safety protection for the tires.
