What is the normal unit for tire pressure?
1 Answers
The normal unit for tire pressure is atmospheric pressure in kPa. The standard atmospheric pressure is 101 kPa, and typical tire pressure is around 2.5 times atmospheric pressure. Strictly speaking, tire pressure refers to the air pressure inside the tire. In automotive maintenance, the engine is the heart of the car—its failure can lead to the end of the vehicle's lifespan—while tire pressure is like the car's blood pressure. The level of tire pressure plays a crucial role in the car's performance and power. Higher tire pressure can improve fuel efficiency and make steering lighter, but it is also more dangerous, as even small bumps can cause a blowout. Lower tire pressure increases contact with the road, improving braking and cornering grip, but it can lead to sidewall deformation, accelerated aging, and safety risks, while also increasing fuel consumption. It is recommended that car owners regularly check their tire pressure.
