The normal tire pressure range for GAC Trumpchi GS4 is 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 requirements. The tire pressure monitoring system for GAC Trumpchi GS4 can be viewed on the dashboard. The factory-installed tire pressure monitoring system provides automatic alarm alerts without manual operation. Lower trim models may not come with this feature and require aftermarket installation. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates uneven wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches tire cords, reducing elasticity and increasing driving load. Hazards of underinflated tires: Increased friction with the road surface, leading to higher fuel consumption; causes heavy steering and deviation, compromising driving safety; increases movement of tire components, leading to excessive heat buildup; weakens cord and rubber functionality, causing delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction with the ground, sharply raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a blowout. If the tire pressure monitoring indicator light illuminates (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), there are generally three possible causes: Abnormal tire pressure: Typically triggers an alarm when below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the system retains the old data, causing the indicator light to stay on. Simply reset the tire pressure to resolve this. Damaged tire pressure 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 tire pressure warning light will activate. A damaged sensor must be replaced with a new one.
