What is the proper tire pressure for a sedan?
1 Answers
For small cars, the normal standard tire pressure is between 2.2-2.5 bar. Below is an introduction about tire pressure: 1. Normal range: The appropriate tire pressure is between 2.3~2.7 BAR. In summer, when temperatures are high, the tire pressure may rise above 3.0 BAR after driving, so a summer tire pressure value between 2.3~2.5 BAR is more suitable. 2. Over-inflation: Over-inflation reduces tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; makes tires more susceptible to punctures from sharp objects like nails or glass, leading to internal cracks, blowouts, and potential tire bursts. 3. Under-inflation: Increases friction with the road surface, raising fuel consumption; causes heavy steering and deviation, posing risks to driving safety; increases movement in various tire parts, leading to abnormal heat generation from excessive rolling; multiplies friction with the ground, rapidly raising tire temperature, softening the tire, and drastically reducing strength, which can cause blowouts during high-speed driving; under-inflation increases tire deformation, making the sidewalls prone to cracks and causing flexing movements, leading to excessive heat, rubber aging, ply fatigue, and cord breakage, while also increasing the tire's contact area with the ground, accelerating shoulder wear.
