Is the tire pressure of 2.2bar normal for Changan CS55?
4 Answers
Changan CS55 tire pressure of 2.2bar is not normal, as the tire pressure is low. The normal tire pressure for Changan CS55 should be within the range of 2.3 to 2.5bar. The effects of low tire pressure include: 1. Causing the steering wheel to feel heavy and prone to deviation, reducing driving safety; 2. Increased friction between the tire and the ground, leading to higher tire temperature, softening of the tire, and reduced strength; 3. Decreased functionality of the cords and rubber; 4. Increased deformation of the tire body, making the tire side prone to cracks. The dimensions of the Changan CS55 are: length 4500mm, width 1855mm, height 1690mm, with a wheelbase of 2650mm, a fuel tank capacity of 58 liters, and a body weight of 1460kg.
I've been driving a Changan CS55 for several years, and tire pressure is something you really can't take lightly. The general recommended value is around 2.3 to 2.4 bar, depending mainly on the vehicle model and tire size. For example, with 18-inch wheels, the standard pressure is a bit higher. 2.2 bar is slightly on the low side, which might accelerate tire wear, make the ride feel a bit softer, and could increase fuel consumption by 5-10%. In the long run, it's not an ideal state. Measuring when cold is more accurate; it's best to check after the car has been parked overnight. The specific values are usually labeled on a sticker by the door—too high affects comfort, and too low increases risks like tire blowouts. Personally, I make it a habit to use a digital pressure gauge to check monthly, keeping it at the recommended value for peace of mind. If you don’t have the tools, you can always get a free check at a gas station. Safe driving depends on these small details, so don’t overlook them during regular maintenance.
From my years of driving experience, the normal tire pressure range for the Changan CS55 is typically most suitable at 2.3-2.4 bar. A reading of 2.2 bar is slightly low, which may not be a major issue but is worth adjusting. Insufficient pressure can lead to lower tire pressure, increased tire contact area, higher rolling resistance resulting in increased fuel consumption, and may cause uneven wear on the tire edges during long-distance driving. Measuring when the tires are cold is more accurate; after driving, the pressure may rise to 2.5 bar, which is normal. It's advisable to quickly refer to the manual to confirm the standard values and maintain them within a ±0.1 bar margin. Checking it yourself is simple: after parking, use a portable pressure gauge to take a few measurements, ensuring it's neither too high nor too low to affect handling and stability. Make it a regular habit to protect your tires and save on fuel and costs.
Regarding the tire pressure of Changan CS55, 2.2 bar is slightly lower than the commonly recommended range of 2.3-2.4 bar, which may be a bit low but still acceptable. Tire pressure affects driving experience: too low makes driving laborious and increases fuel consumption, while too high results in a bumpy and uncomfortable ride. The most accurate measurement is taken when the tires are cold, so let the car sit for a while before checking. The standard values are indicated on the sticker on the door frame; adjust accordingly with an error margin not exceeding 0.2 bar. I always carry a small tire pressure gauge with me and check the pressure weekly for maintenance. Driving with insufficient pressure for a long time can easily damage the tires and compromise safety. Adjust early when needed, and develop good habits for convenience and safety.
