What is the normal tire pressure for a Highlander?
1 Answers
The normal tire pressure for a Highlander is between 2.2~2.5 bar. In winter, the tire pressure can be slightly increased by about 0.2 bar based on the standard value, while in summer, it can be slightly reduced by about 0.1 bar to prevent tire blowouts due to high temperatures. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear on the central tread of the tire, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, leading to internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, posing safety risks; Increases movement of tire parts, leading to abnormal heat buildup due to excessive rolling; Weakens the cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; Dramatically increases friction with the ground, raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may lead to blowouts; Increases tire deformation, leading to sidewall cracks and excessive flexing, which generates heat, accelerates rubber aging, fatigues the cord layers, and causes cord breakage. It also increases the tire's contact area, accelerating shoulder wear.
