What is the suitable tire pressure for Wuling Hongguang in summer?
2 Answers
Wuling Hongguang's suitable tire pressure in summer 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 follows the international GBT2978-2008 standard requirements. The tire pressure monitoring system in Wuling Hongguang S can be checked by pressing the tire pressure monitoring button on the center console area. The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire pressure. It transmits the pressure information from inside the tire to the central receiver module via wireless transmitters and then displays the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or there is a leak. Generally, a tire pressure above 2.8 bar is considered too high, and below 2.0 bar is too low. Hazards of excessive tire pressure: Reduced tire friction and adhesion, 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; overextends tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of insufficient tire pressure: Increases friction coefficient with the road surface, raising 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 and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction between the tire and ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a tire blowout. 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), it is generally due to one of the following three reasons: Abnormal tire pressure: Typically, an alarm is triggered when pressure is 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 in time, the system records the previous data, causing the indicator light to turn on. Simply reset the tire pressure to resolve this. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the inflation valve. If the sensor is damaged due to impact while driving, the tire pressure fault light will illuminate. For sensor damage, the only solution is to replace it with a new one.
When driving the Wuling Hongguang in summer, I pay special attention to tire pressure as it directly affects driving safety and comfort. During hot weather, air expands when heated and contracts when cooled. If the tire pressure is too high, the tires become harder and more prone to wear, increasing the risk of a blowout, especially at high speeds. The standard tire pressure for the Wuling Hongguang is usually indicated on the label inside the door frame, such as 2.2 to 2.4 bar for the front tires and 2.4 to 2.6 bar for the rear tires. However, in summer, I recommend checking the pressure when the tires are cold and setting it around 2.3 bar for the front tires and below 2.5 bar for the rear tires. This ensures a smoother ride and reduces tire damage caused by overheating. I use a tire pressure gauge to check the pressure monthly, especially before long trips, to ensure the tires are in good condition. This small habit makes the car more responsive and gives me greater peace of mind while driving.
