What is the normal tire pressure for SUV vehicles?

[Grace]

The tire pressure for SUV tires is typically between 2.2-2.5 bar. Both overinflation and underinflation can have negative effects. For specific details, please refer to the vehicle's manual. Tire pressure is an indicator of a vehicle's load capacity. The load capacity depends on the level of tire pressure. According to the relationship between the tire's load index, pressure, and load capacity, higher tire pressure increases load capacity, while lower pressure reduces it. Overinflated tires are more prone to blowouts, especially during high-speed driving in summer. It can also increase vehicle jolts, affecting driving comfort and safety. The tire's contact area with the ground decreases, accelerating wear in the middle of the tire. Reduced grip can lead to skidding and longer braking distances. Underinflated tires increase contact with the ground, causing overheating, accelerating rubber aging and wear, increasing rolling resistance, reducing the vehicle's top speed, and increasing fuel consumption. Drivers should adjust tire pressure according to external environmental temperatures and driving conditions. In summer, high temperatures can cause tires to heat up, and high pressure increases the risk of blowouts, so pressure should be slightly lower. In winter, tire pressure should be slightly higher than in summer. On smooth roads, maintain normal tire pressure. On unpaved roads, reducing tire pressure ensures better grip and helps avoid punctures from sharp objects.
