What is the normal atmospheric pressure for cars in kPa?
1 Answers
Normal atmospheric pressure for cars is generally within the range of 230-250 kPa. Below are the relevant details: 1. Car tire pressure: The specific normal tire pressure should be based on the manufacturer's recommended value, which can be found in the car's user manual, on the label near the driver's door (B-pillar), in the drawer next to the driver's seat, or on the fuel tank cap. According to the international GBT2978-2008 standard, the standard car tire pressure is calculated in bar and ranges between 210-260 kPa, adjusted based on actual driving experience (lower for comfort, higher for full load/high-speed driving). It is recommended to use 220 kPa for daily driving and 240 kPa for SUVs. 2. Factors affecting tire pressure: Tire pressure is also significantly influenced by seasonal factors. In summer, high temperatures can cause tires to heat up during driving, and high pressure can lead to blowouts, so the pressure should be slightly lower. In winter, tire pressure should be slightly higher than in summer due to thermal contraction and expansion, so a suitable range for car tire pressure in winter is between 250 kPa and 280 kPa.
