What is the suitable tire pressure for Changan CS75?
2 Answers
The recommended tire pressure range for Changan CS75 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 complies with the international GBT2978-2008 standard. The Changan CS75 tire pressure monitoring system information is displayed on the dashboard LCD screen. When one or more tires are significantly underinflated, a warning light will illuminate. If the low tire pressure warning light comes on, you should stop and check the tires as soon as possible under safe conditions, and inflate them to the correct tire pressure. Generally speaking, a tire pressure exceeding 2.8bar is considered too high, while a tire pressure below 2.0bar is considered too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread pattern, shortening tire lifespan; increased vehicle vibration, indirectly affecting the lifespan of other components; excessive stretching of tire cords, reducing tire elasticity, and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; causing heavy steering and deviation, compromising driving safety; increased movement of tire parts, leading to abnormal heat due to excessive rolling; reduced functionality of cords and rubber, causing delamination or cord breakage, excessive friction with the rim, damaging the bead area, and abnormal wear; multiplied friction between the tire and the ground, sharply rising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts. If the tire pressure monitoring indicator light comes on (a yellow symbol, an irregular circle with no stamp on top, four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, it will alert when 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 was not reset in time, causing the tire pressure monitoring system to still record the previous data, and the tire pressure monitoring indicator light will remain on. At this time, simply reset the tire pressure. 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 due to impact while driving, the tire pressure fault light will also illuminate. For sensor damage issues, only replacement with a new part is possible.
I've been driving the Changan CS75 for several years, and maintaining tire pressure between 2.3 to 2.5 bar is most suitable. If it's too high, the ride feels very bumpy and traction suffers; if it's too low, tires wear out more easily and the risk of blowouts increases. Seasonal changes also require attention. In hot summers when tire pressure naturally rises, I usually inflate to 2.3 bar to prevent it from getting too high. In cold winters, it drops to around 2.2, and I adjust it back to 2.4 or 2.5 after the car warms up. I make it a habit to check once a month with a simple tire pressure gauge—it only takes a few minutes. There's a label on the car door frame recommending 2.3-2.5, which I follow. Once, I neglected the tire pressure when it was a bit low, and fuel consumption noticeably increased, with the car feeling unstable in turns. Now, I've developed a habit of checking the tires before driving and addressing any noticeable deflation promptly—it's safer and more fuel-efficient. Keeping the tires in good condition also extends the car's lifespan.
