What is the normal tire pressure for SUVs in summer?

[LeJaxson]

SUV tire pressure in summer is generally between 2.3-2.4 bar. The normal tire pressure range for cars is 2.4-2.5 bar. Due to seasonal factors, winter tire pressure can be appropriately increased by 0.2 bar, while summer tire pressure can be reduced by 0.1 bar. This data is based on the international GBT2978-2008 standard requirements. Generally speaking, tire pressure exceeding 2.8 bar is considered too high, while tire pressure below 2.0 bar is considered too low. The hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends tire cords, reducing elasticity and increasing the load on the vehicle during driving. The hazards of insufficient tire pressure: Increases friction coefficient with the road surface, raising fuel consumption; Makes steering heavy and prone to deviation, compromising driving safety; Increases movement in various tire parts, causing abnormal heat due to excessive rolling; Weakens cord and rubber functionality, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction with the ground, sharply increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in tire blowouts.
