Is a tire pressure of 228 normal?
2 Answers
A tire pressure of 228 kPa is not normal. The normal range for tire pressure is between 230 kPa and 250 kPa. Driving with low tire pressure can cause severe tire wear and, in serious cases, may lead to a tire blowout. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening its lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing the elasticity of the tire body and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, leading to internal cracks or blowouts. Methods to address insufficient tire pressure: If no damage is visible, simply inflate the tire to the normal pressure and reset the tire pressure system; If a puncture is found during inspection, drive to a tire shop for repair and then reinflate; If the tire pressure warning reappears after inflation without any visible puncture, it may be due to a leaking rim caused by deformation. It is recommended to inspect and replace the rim if necessary.
My car has been running for over ten years, and a tire pressure of 228 kPa is generally not considered low. Most vehicles recommend a range between 200 to 250 kPa on the door pillar or in the manual. For example, my old car suggested 230 kPa. In winter, when temperatures drop, I inflate to around 240 kPa for balance, and in summer, I might reduce it to 220 kPa to prevent blowouts. Too high pressure can cause rapid wear in the center of the tire and a bumpy ride, while too low pressure increases fuel consumption and wears the edges of the tires faster. Every time I refuel, I bring a tire pressure gauge to check all tires, including the spare, ensuring uniformity. If 228 kPa is measured when the tires are cold, it's generally fine, but it's best to confirm your car's specific recommended value, as it varies significantly between models—SUVs might need higher pressure. Regular monitoring can extend tire life by over five years, something I've personally tested and found effective, saving me a lot on repair costs.
