What is the normal tire pressure for Changan CS55?
2 Answers
The normal tire pressure range for Changan CS55 is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and decreased by 0.1bar in summer. This data complies with the international GBT2978-2008 standard. If you want to know the current tire pressure of your Changan CS55 during daily driving, you can activate the tire pressure monitoring system, and the tire pressure value will be displayed on the central LCD screen of the instrument panel. The specific method is to press the LCD adjustment button on the left combination meter of the steering wheel to switch to the tire pressure monitoring system interface. Generally speaking, a tire pressure exceeding 2.8bar is considered too high, and a tire pressure below 2.0bar 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; the vehicle's vibration increases, indirectly affecting the lifespan of other components; it can cause excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the vehicle 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, which are factors detrimental to driving safety; it increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; it reduces the functionality 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. If the vehicle is driven at high speed, it may lead to a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol, an irregular circle with no stamp on top and four small spikes at the bottom, with an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, it will alert if the pressure is below 1.8bar or above 3.0bar. At this time, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, the tire pressure monitoring system was not reset in time, causing it to still record the previous data, which will trigger the tire pressure monitoring indicator light. At this time, simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged during driving, it will also cause the tire pressure warning light to come on. For sensor damage issues, only a new replacement part can be used.
I've been driving the Changan CS55 for almost three years and deeply understand the importance of tire pressure for safe driving. Normal tire pressure typically ranges between 2.3 to 2.5 bar, but you should always check the label on the door frame or the user manual for specifics. I use a simple tire pressure gauge to check it every month, preferably when the car is cold—meaning after it's been parked overnight before driving. If the pressure is too low, the tires can overheat and risk a blowout, plus braking distance increases. If it's too high, the ride becomes bumpy, and the risk of skidding in rainy conditions rises. In summer, when temperatures rise, the tire pressure tends to increase, so I often release a bit of air to bring it back to around 2.4. In winter, I add a little more. Safety comes first, so I recommend checking tire pressure regularly to avoid accidents, especially before long trips—don't overlook this small but crucial detail.
