What is the normal tire pressure for the Hongqi HS5?

[McMichael]

The normal tire pressure for the Hongqi HS5 is between 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and decreased by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. The tire pressure display for the Hongqi HS5 is located on the right-hand side of the steering wheel. By toggling the wheel, you can check the car's tire pressure. The tire pressure monitoring system (TPMS) technology can automatically monitor various tire conditions in real-time by recording the tire's rotation speed or through electronic sensors installed in the tires, providing effective safety assurance while driving. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a pressure below 2.0 bar is too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, 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; overstretches the tire cords, reducing elasticity and increasing the load on the car during driving. Hazards of underinflated tires: 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; reduces the functionality of cords and rubber, leading to delamination or cord breakage, excessive friction with the rim, causing damage to the bead area and abnormal wear; exponentially increases friction with the ground, rapidly raising tire temperature, softening the tire, and drastically reducing 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 at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, an alarm is triggered if the pressure is below 1.8 bar or above 3.0 bar. In this case, a 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 tire pressure monitoring light to stay on. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, the tire pressure warning light will illuminate. For sensor damage issues, only a complete replacement with a new part will suffice.

I've been driving the Hongqi HS5 for two years now, and tire pressure is quite important. The normal tire pressure should be between 230 to 250 kPa, equivalent to 2.3 to 2.5 bar, and this specific value can be found on the label on the driver's side door frame or in the user manual. I make it a habit to check it every two weeks, for example, using a portable tire pressure gauge. This ensures even tire wear, improves grip, and can even save some fuel costs. If the pressure is too high, the tires become stiff, increasing braking distance and making turns less stable; if it's too low, the tires can overheat and risk a blowout, especially on long trips. Last time before a highway drive, I adjusted the tire pressure and felt the car was more stable—safety first, after all. I recommend fellow drivers to maintain it regularly and not overlook this small but crucial detail.
