Should Tire Pressure Be Higher or Lower in Hot Weather?

[McEzra]

In hot weather, tire pressure tends to increase. You can adjust it to the lower limit of the standard tire pressure based on the vehicle's load. The standard tire pressure for sedans is usually indicated on the B-pillar near the front doors or on the fuel tank cover. Adjust it to around 2.1 to 2.3 bar. Standard Tire Pressure: For standard tires, the standard pressure is 240-250 kPa, while for reinforced tires, it is 280-290 kPa. Since most vehicle tires fall under the standard category as per international regulations, this is why 4S shops generally inflate tires to 2.5 bar (1 bar = 100 kPa). Summer Tire Precautions: Regularly check tire pressure and inflate according to standard values; inspect tire conditions periodically to avoid bulges, punctures, and excessive wear; do not cool extremely hot tires with cold water, as extreme temperature changes and shocks can accelerate tire aging and reduce lifespan—allow them to cool naturally.
