What is the appropriate tire pressure for an Accord?
1 Answers
The normal tire pressure range for an Accord 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 Accord's tire pressure monitoring system is an indirect type, which only provides a tire pressure warning. When the tire pressure is too low, the tire pressure warning light will illuminate. The indirect tire pressure monitoring system determines whether the tire pressure is normal through wheel speed sensors. Generally, a tire pressure above 2.8 bar is considered too high, and a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern of the tire, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; causes excessive stretching and deformation of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; causes heavy steering and deviation, posing risks to driving safety; increases movement of various parts of the tire, leading to excessive rolling and abnormal heating; reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction between the tire and the ground, sharply increasing 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 illuminates (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Typically, it will alert if the 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 will still record the previous data, causing the tire pressure monitoring light to illuminate. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is directly installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving (e.g., by hitting a curb), the tire pressure warning light will also illuminate. For sensor damage issues, only a complete replacement of the component is possible.
