What is the recommended tire pressure for the xrv?
1 Answers
The normal tire pressure range for the xrv is around 2.3-2.5 bar. According to the international standard GBT2978-2008, the recommended tire pressures for different tire types are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. Hazards of over-inflation: 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 driving load; Decreases puncture resistance, making tires more susceptible to damage from sharp objects like nails or glass, potentially causing blowouts. Hazards of under-inflation: Increases friction with the road surface, raising fuel consumption; Makes steering heavier and more prone to deviation, compromising safety; Increases movement of tire components, causing abnormal heat from excessive compression; Weakens cord and rubber functions, leading to delamination or cord breakage and excessive friction with the rim, causing damage and abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength, which can cause blowouts at high speeds; Increases tire deformation, leading to sidewall cracks, excessive heat from flexing, rubber aging, cord fatigue, and accelerated shoulder wear.
