According to the international GBT2978-2008 standard, the recommended tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: Should not exceed 3.5bar. Hazards of overinflated tires: 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; Overstretches tire cords, reducing elasticity and increasing vehicle load during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate, causing internal cracks or blowouts. Hazards of underinflated tires: Increases friction 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 parts, causing abnormal heat due to excessive rolling; Weakens cord and rubber functions, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area; Multiplies friction with the ground, rapidly increasing tire temperature and softening the tire, drastically reducing strength. High-speed driving may cause blowouts; Increases tire deformation, causing sidewall cracks and flexing movements, leading to overheating, rubber aging, cord fatigue, and accelerated shoulder wear.
