What is the normal tire pressure for the Edge?

[LeKaleb]

The normal tire pressure range for the Edge 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. When one or more tires are significantly underinflated, a warning light will illuminate. If the low tire pressure warning light comes on, you should stop and check the tires as soon as it is safe to do so, and inflate them to the correct pressure. 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 friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and misalignment, reducing driving comfort; accelerates localized wear of the tread center, 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 while driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; causes heavy steering and misalignment, compromising driving safety; increases movement of tire components, leading to abnormal heat generation due to excessive rolling; reduces the functionality of 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 friction between the tire and the ground, rapidly 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 comes on (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, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, the tire pressure was not reset in time, causing the system to still record the previous data, which triggers the tire pressure monitoring indicator light. 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 tire inflation valve. If the sensor is damaged due to impact while driving, it can also trigger the tire pressure warning light. For sensor damage, the only solution is to replace it with a new one.

I've been driving the Edge for several years. The normal tire pressure range is usually between 32 to 35 PSI, but you should always check the sticker on the door frame or the owner's manual for specifics. I make it a habit to check the pressure monthly with a tire gauge, and only when the tires are cold for accurate readings. Remember, underinflation increases fuel consumption, accelerates tire wear, and in severe cases can lead to blowouts, compromising driving safety. Overinflation, on the other hand, makes the ride bumpy and reduces traction. Especially in summer when temperatures rise, tire pressure can increase by 2-3 PSI, so I let out a bit of air. In winter, it drops, and I top it up slightly. I find maintaining around 32 PSI ideal for balancing comfort and fuel efficiency. In short, don't neglect it—proper tire pressure extends tire life, saving you hassle and money.
