What is the normal tire pressure range for SUVs?

[GriffinRose]

The normal tire pressure for SUVs is generally maintained between 2.2-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard requirements. Strictly speaking, tire pressure refers to the air pressure inside the tire. Tire pressure is the blood pressure of a car, and its level plays a crucial role in the car's performance and power. Tire pressure is an important factor affecting the service life and economy of tires. If you want to know the normal tire pressure value for your car, you can check the vehicle's user manual or the label next to the door B-pillar, as well as the tire pressure value marked on the inside of the fuel tank cap. Generally speaking, a tire pressure exceeding 2.8 bar is considered too high, and a tire pressure below 2.0 bar is considered too low. Hazards of excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear of the tread pattern in the center of the tire, shortening the tire's lifespan; it increases body vibration, indirectly affecting the lifespan of other components; it causes excessive stretching deformation of the tire cords, reducing the elasticity of the tire body, and increasing the load on the car during driving. Hazards of insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, creating unsafe driving conditions; it increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; it reduces the function of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; the friction between the tire and the ground increases exponentially, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under these conditions may lead to a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, it will alert if the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are needed. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to light up. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which is used to monitor tire pressure, is directly installed inside the tire and connected to the tire inflation port. If the sensor is damaged due to impact while driving, it can also cause the tire pressure warning light to come on. For sensor damage issues, the only solution is to replace it with a new component.
