What is the normal tire pressure for the Changan Benben car?
2 Answers
The normal tire pressure range for the Benben is 2.4-2.5 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. To check the tire pressure of the Benben, first prepare a tire pressure gauge, locate the position of the original tire pressure label, press the tire pressure gauge against the tire valve to measure and read the value. After measuring, remember to cover the valve cap. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar 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 pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of insufficient tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; causes heavy steering and deviation, compromising driving safety; increases movement of tire components, leading to excessive rolling and abnormal heat generation; weakens the function of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction with the ground, sharply raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may lead to tire blowouts. If the tire pressure monitoring indicator lights up (a yellow symbol, an irregular circle with no seal on top and four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Typically, 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 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 to light up. Simply reset the tire pressure to resolve this. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged during driving, the tire pressure warning light will illuminate. For sensor damage, replacement with a new part is the only solution.
The standard tire pressure for the Changan Benben is generally between 2.2 and 2.5 bar, which is a common range. The specific value can be found clearly on the label on the driver's door frame or in the owner's manual. I drive a Benben myself and often check the tire pressure. Keeping it at 2.3 bar when the tires are cold is most suitable. During seasonal changes, such as high temperatures in summer, a slightly higher tire pressure is acceptable, but in winter, it's best to adjust it closer to the lower limit to avoid slipping. Excessive tire pressure causes faster wear in the middle of the tire, while low pressure increases fuel consumption and the risk of a blowout. I recommend checking it with a simple tire pressure gauge every two weeks—the tool is cheap and convenient, available online for just twenty yuan. When the car is loaded with more people or heavy items, the tire pressure should be higher; for normal driving, a medium level is fine. Never be lazy about this, as it directly affects safety and tire lifespan.
