The normal tire pressure range for Wuling Hongguang mini 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 is based on the requirements and standards of the international GBT2978-2008. The tire pressure monitoring of Wuling Hongguang mini can be checked by pressing the tire pressure monitoring button in the central console area. Its tire pressure monitoring is installed on the tires and is indirect. When the tire pressure decreases, the vehicle's weight will cause the tire diameter to decrease, resulting in a change in vehicle speed. This change in speed will trigger the WSB alarm system, thereby alerting the owner to insufficient tire pressure. Generally, a tire pressure exceeding 2.8bar is considered too high, while 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 will cause steering wheel vibration and deviation, reducing driving comfort; it will accelerate local wear of the tread pattern in the center of the tire, reducing tire life; vehicle vibration will increase, indirectly affecting the lifespan of other components; it will cause excessive stretching deformation of the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving. Hazards of insufficient tire pressure: The friction coefficient with the road surface will increase, leading to higher fuel consumption; it will cause heavy steering and deviation, posing risks to driving safety; it will increase the movement of various parts of the tire, causing abnormal heating due to excessive rolling; it will reduce the function 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 will multiply, causing a sharp rise in 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 with an irregular circle, no seal on top, four small spikes below, and an exclamation mark inside), there are generally three reasons: Abnormal tire pressure: Generally, it will alarm 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, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the original data, causing the tire pressure monitoring indicator light to come 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 during driving, it will also cause the tire pressure fault light to come on. For sensor damage issues, only a new replacement part can be used.

I drive my Wuling Hongguang MINI every day to pick up and drop off my kids at school, and maintaining a tire pressure of around 2.5 bar feels the most comfortable. The city roads often have potholes, and if the tire pressure is too high, the ride gets too bumpy, making my kids complain of dizziness; too low, and it wastes fuel and increases braking distance. I make it a habit to check the tire pressure every two weeks with a simple tire gauge, especially during seasons with significant temperature changes. In summer, the tire pressure can rise to 2.6 bar, so I just let out a bit of air to bring it back to 2.5 bar; in winter, I add a little to reach 2.4 bar. Don’t underestimate this—proper tire pressure can save about 10% on fuel and extend tire life by several years. The manual recommends a range of 2.3-2.8 bar, but in practice, I find 2.5 bar to be the most stable. Each check takes just two minutes—safe and cost-effective.

As someone who frequently tinkers with my beloved car, I recommend setting the tire pressure for the Wuling Hongguang MINI between 2.4 to 2.6 bar. The exact values can be found in the manual or on the door frame label. This car comes with a built-in tire pressure monitoring system that alerts for abnormalities, but using a digital tire pressure gauge for regular checks provides more precise readings. Low tire pressure increases rolling resistance, significantly raising fuel consumption; while overinflation reduces comfort and may accelerate tire wear. I've installed a wireless tire pressure monitor that displays real-time data on the dashboard, making adjustments convenient. Standards vary with different loads—when fully loaded, a slight adjustment to 2.7 bar is advisable. Consistently calibrating once a month optimizes grip, ensuring safer driving in rainy conditions. From a technical perspective, this is the most fundamental vehicle maintenance.

My Wuling Hongguang MINI has been running for over six months, and maintaining tire pressure at 2.5 bar is the money-saving trick. For an economy car, fuel efficiency is key. When the tire pressure drops below 2.3 bar, fuel consumption spikes, wasting gas and damaging tires; exceeding 2.7 bar increases risks like bumpy rides or loss of control. I bought a tire pressure gauge for just over ten yuan, checking weekly—it takes mere minutes to ensure optimal pressure. This routine saves me dozens of yuan monthly on fuel and avoids extra costs from premature tire replacements. Safety-wise, it’s fundamental: proper pressure prevents blowouts. For regular driving, sticking to this range works perfectly.
