At what tire pressure level should a car be inflated?
1 Answers
During summer, tires should be inflated when the pressure falls below 2.0 bar, while in winter, inflation is necessary when the pressure drops below 2.2 bar. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and misalignment, diminishing driving comfort; accelerates uneven wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly impacting the longevity of other components; overstretches tire cords, reducing elasticity and increasing driving load; decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, and impacts may cause internal cracks or blowouts, leading to tire failure. Hazards of underinflated tires: Increases friction coefficient with the road surface, raising fuel consumption; makes steering heavier and prone to misalignment, compromising driving safety; increases movement in various tire sections, causing abnormal heat due to excessive compression; degrades cord and rubber functionality, leading to delamination or cord breakage and excessive friction with the wheel rim, damaging the bead area and causing abnormal wear; multiplies friction between the tire and ground, sharply increasing tire temperature and softening the tire, drastically reducing strength. High-speed driving may result in blowouts; increases tire body deformation, making sidewalls prone to cracks and generating flexing motion, leading to excessive heat, rubber aging, cord fatigue, and breakage, while also enlarging the tire's contact area and accelerating shoulder wear.
