What is the normal tire pressure for a Haval H2?
1 Answers
The normal tire pressure range for the Haval H2 is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and reduced by 0.1bar in summer. This data is based on the international GBT2978-2008 standard requirements. The tire pressure monitoring system in the Great Wall Haval H2 can be checked via the function button on the steering wheel (the up and down paging buttons on the left side of the steering wheel). The tire pressure monitoring system automatically monitors the tire pressure in real-time while driving and alerts the driver to any leaks or low pressure to ensure driving safety. Generally, a tire pressure above 2.8bar is considered too high, and a tire pressure below 2.0bar is considered too low. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread of the tire, shortening its lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle while driving. Hazards of insufficient tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; weakens the function of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in 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 below, and an exclamation mark inside), it is generally due to one of the following three reasons: Abnormal tire pressure. The system typically alerts when the pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset. After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the indicator light to remain on. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor. The sensor, which monitors tire pressure, is installed inside the tire and connected to the inflation valve. If the sensor is damaged during driving, the tire pressure warning light will illuminate. In such cases, the only solution is to replace the sensor with a new one.
