Your tire pressure must meet the requirements of the vehicle and tire manufacturer. In general, the inflation pressure of tires varies depending on the vehicle load and usage conditions.
The prescribed air pressure usually refers to the air pressure of a cold tire and cannot be lower than this value. Due to the generation of a lot of heat during driving, the air pressure of hot tires will be higher. Do not lower the tire pressure when the tire is hot, as the air pressure will be lower than the low allowable tire pressure when the tire cools down.
Check and adjust tire pressure (including spare tire, if equipped) every 14 days. It is necessary to check and adjust tire pressure before embarking on a long journey or vacation. According to the manual, additional loads may require higher tire pressure.
