What is the tire pressure range for the Wuling Hongguang Mini?
2 Answers
The normal tire pressure range for the Wuling Hongguang Mini is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. The tire pressure monitoring system (TPMS) of the Wuling Hongguang Mini can be checked by pressing the TPMS button on the center console. The TPMS is installed on the tires and is an indirect system. When the tire pressure decreases, the vehicle's weight causes the tire diameter to shrink, leading to changes in speed, which then triggers the WSB alarm system to alert the driver of insufficient tire pressure. Generally, tire pressure above 2.8 bar is considered too high, and below 2.0 bar is too low. Hazards of overinflated tires: Reduced friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, lowering driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting other components' longevity; overstretches tire cords, reducing elasticity and increasing driving load. Hazards of underinflated tires: Increased friction with the road, leading to higher fuel consumption; makes steering heavy and prone to deviation, compromising driving safety; increases movement of tire parts, causing abnormal heat due to excessive rolling; weakens cord and rubber function, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a tire blowout. If the TPMS warning light (a yellow symbol with an irregular circle, no seal on top, four small spikes below, and an exclamation mark inside) illuminates, there are generally three possible reasons: Abnormal tire pressure: Typically alerts when below 1.8 bar or above 3.0 bar. In this case, check the tires and adjust the pressure. TPMS not reset: After inflating the tires, failing to reset the TPMS promptly causes the system to retain old data, triggering the warning light. Simply reset the TPMS. Damaged TPMS sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If damaged during driving (e.g., by impact), the TPMS warning light will activate. A damaged sensor must be replaced.
I used to drive a Wuling Hongguang Mini, and its standard tire pressure range is generally between 2.2 and 2.5 bar, depending on the label or manual in the car. I prefer to check it myself with a tire pressure gauge when the car is cold. During hot summers, I keep it around 2.2 to avoid excessive expansion and blowouts, while in winter, I increase it to 2.4 for better traction. When I first got the car, the dealer reminded me that maintaining this range saves fuel and extends tire life, so checking it every two weeks has become my routine. Also, remember that insufficient tire pressure increases tire wear and the risk of wheel deformation, so always check before long trips—safety first.
