Is the tire pressure high or low in hot weather?

In hot weather, the tire pressure is easy to rise, which can be adjusted to the lower limit of the standard tire pressure according to the vehicle load. The general standard tire pressure vehicle is located at the B-pillar position on the front door or the fuel tank cover, and it is adjusted to about 2. 1~2.3bar: the standard tire pressure is 240-250kPa, and the standard tire pressure of reinforced tires is 280-290kPa. The tires on which most models are based belong to the standard tires in international regulations, so this is also the reason why 4S stores generally raise the tire pressure to 2.5 bar (1bar =100 kpa). Precautions for tires in summer: check the tire pressure regularly and inflate the tires according to the standard value; Check the tire condition regularly to avoid bulging, puncture and excessive wear; There is no need to cool extremely hot tires with cold water. Extreme temperature changes and stimuli will accelerate tire aging and affect its service life, so it can be cooled naturally.
