What is the normal tire pressure for SUVs in summer?
1 Answers
The tire pressure for SUVs 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, tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard requirements. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a 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 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, leading to higher fuel consumption; Makes the steering wheel heavy and prone to deviation, compromising driving safety; Increases movement of tire components, causing abnormal heat due to excessive rolling; Weakens cord and rubber functions, leading to delamination or cord breakage, excessive friction with the rim causing damage to the bead area, and abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout.
