The customers ask us whether they need to reduce the pressure of tire in Summer. Because they are afraid that tires are cracked. It’s correct in thinking. The tire manufacturer tells you that if pressure is within the standard range, you needn’t to adjust the tire’s pressure in summer or winter. But if the tire’s pressure is high in summer, the tires are cracked easily. If high pressure is inflated in winter, the tire contact length is reduced. And the low pressure will affect the vehicle’s fuel consumption and increase contact length. So please inflate with tires according to tire manufacturer request.
