What is the tire pressure in kPa?
2 Answers
Tire pressure is between 240 and 250 kPa, which refers to the air pressure inside the tire. Hazards of excessive tire pressure: 1. The friction and adhesion of the tire will decrease, affecting braking performance; 2. It may cause steering wheel vibration and deviation, reducing driving comfort; 3. Accelerates localized wear of the tread center pattern, shortening tire lifespan; 4. Increases vehicle vibration, indirectly affecting the lifespan of other components. Factors affecting tire pressure: 1. Seasonal factors: In winter, the tire pressure can be appropriately increased by 0.2 bar based on the standard tire pressure; in summer, when the car is parked outdoors, the pressure can be 0.1 bar lower than the standard to prevent high-temperature blowouts; 2. Tire pressure measurement conditions: Cold tires and hot tires have different pressures, and the difference between them should be noted as 0.3 bar during measurement.
Having driven for over twenty years, I can't stress enough how important tire pressure is. The specific value varies by vehicle, with ordinary sedans typically recommended between 210 to 240 kPa. My old sedan, for example, has it marked at 220 kPa on the door frame. Too low pressure wears tires out quickly and wastes fuel; too high pressure makes tires stiff, leading to uncomfortable driving and even the risk of a blowout. Remember to check with a simple pressure gauge monthly, especially before long trips, and adjust by adding or releasing air. This enhances safety and extends tire life—don't wait until problems arise, which is costly and dangerous. New drivers often ask what to do; the best approach is to check the user manual or look up the model's standard value online. Never adjust it based on guesswork.
