What is the appropriate tire pressure for the GS4 car?
1 Answers
The normal tire pressure range for the GS4 car is 2.3~2.7bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and decreased by 0.1bar in summer. This data is based on the international GBT2978-2008 standard requirements. Generally speaking, a tire pressure exceeding 2.8bar is considered too high, and a tire pressure below 2.0bar is considered too low. Tire pressure monitoring is mainly divided into two types: indirect tire pressure monitoring and direct tire pressure monitoring. Direct tire pressure monitoring: Uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is sent from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. When the tire pressure is too low or there is a leak, the system will automatically alert. Indirect tire pressure monitoring: When the pressure of a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in its rotation speed being faster than the other wheels. By comparing the differences in rotation speeds between tires, the system monitors the tire pressure. Indirect tire pressure alert systems actually rely on calculating the rolling radius of the tire to monitor the pressure. Hazards of overinflated tires: Reduced friction and adhesion of the tire, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread of the tire, reducing tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; causes excessive stretching deformation of the tire cords, reducing tire elasticity, and increasing the load on the vehicle while driving. Hazards of underinflated tires: Increases the friction coefficient with the road surface, leading to higher fuel consumption; causes the steering wheel to feel heavy and prone to deviation, among other factors detrimental to driving safety; increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; reduces the functionality 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; multiplies the friction between the tire and the ground, causing a sharp rise in 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 is on, there are generally three reasons: Abnormal tire pressure: Generally, it will alert when 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 previous data, causing the tire pressure monitoring indicator light to turn on. At this point, 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 turn on. For sensor damage issues, only a complete replacement of the part is possible.
