What is the appropriate cold tire pressure for an SUV?
1 Answers
The recommended cold tire pressure for an SUV is generally within the range of 2.2-2.5 bar. However, to determine the exact normal tire pressure for your specific SUV model, you should refer to the vehicle's user manual or check the manufacturer's recommended values indicated on the label near the door (around the B-pillar or C-pillar). Hazards of overinflated tires: 1. Excessive tire pressure reduces tire friction and adhesion, negatively impacting braking performance and shortening tire lifespan. 2. Overinflation decreases puncture resistance, increasing the risk of blowouts. 3. Accelerates uneven wear on the central tread pattern, reduces tire durability, amplifies vehicle vibration, and indirectly affects the longevity of other components. 4. Overinflation causes excessive stretching deformation of tire cords, reduces tire elasticity, increases driving load, and weakens puncture resistance. When encountering sharp objects like nails or glass, the tire becomes more susceptible to penetration, internal cracks, and explosive blowouts. Hazards of underinflated tires: 1. Low pressure increases fuel consumption, makes steering heavier, causes alignment issues, damages bead areas, causes abnormal wear, reduces tire strength, and may lead to blowouts during high-speed driving. 2. Insufficient pressure increases movement in all tire parts, causing excessive rolling that generates abnormal heat, degrading cord and rubber functionality, leading to delamination or cord breakage, and creating excessive friction between the rim and bead area. 3. Multiplies friction with the road surface, causing rapid temperature rise, tire softening, drastic strength reduction, and potential blowouts during high-speed driving.
