Is a tire pressure of 290 kPa normal for the X-Trail?
2 Answers
The tire pressure of 290 kPa for the X-Trail is not normal. According to the international GBT2978-2008 standard, the standard tire pressure should be between 2.4-2.5 bar. A pressure of 2.0 bar is below the minimum standard value, so it is not normal. Hazards of overinflated or underinflated tires: For tires, the pressure should neither be too high nor too low. Overinflation reduces the contact area between the tire and the ground, leading to poor traction and affecting the vehicle's handling and driving stability. Underinflation can cause wave-like deformation of the tire during high-speed driving, which not only shortens the tire's lifespan but also increases the risk of a blowout. Introduction to standard tire pressure: According to the international GBT2978-2008 standard, the recommended tire pressures 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.
I've been driving my X-Trail for several years and usually keep the tire pressure around 240kpa. 290kpa is a bit too high and feels risky. The standard tire pressure for the X-Trail is within the 220-250kpa range, as stated in the owner's manual or the door sticker. I've checked multiple times—excessive tire pressure makes the tires too stiff, causing harsh bumps on rough roads, especially tiring during long drives. It also accelerates wear on the tire edges, leading to higher replacement costs. Safety-wise, it's not ideal either, as reduced contact area increases braking distance and makes the car more prone to skidding in wet conditions. I recommend using a tire pressure gauge to check; if it's still high, release some air to adjust to the manual's recommended value. Remember, both overinflated and underinflated tires affect driving stability, so regular checks are key. I make it a habit to measure every two months, preferably when the tires are cold in summer for the most accurate reading. Developing this habit saves a lot of hassle.
