What is the normal tire pressure range for the Envision 20T?
1 Answers
The normal tire pressure range for the Envision 20T 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 requirements. The Envision 20T is equipped with a direct tire pressure monitoring system (TPMS), which displays real-time tire pressure values on the dashboard. The TPMS technology automatically monitors various tire conditions in real-time by recording tire rotation speeds or through electronic sensors installed in the tires, providing effective safety assurance during driving. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a pressure below 2.0 bar is 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, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increases friction coefficient with the road surface, leading to higher 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; degrades the function 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, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light illuminates (a yellow symbol featuring an irregular circle without a seal, with four small spikes at the bottom and an exclamation mark inside), it is generally due to one of the following three reasons: Abnormal tire pressure: Typically, the system alerts when pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are necessary. TPMS not reset: After inflating the tires, if the TPMS is not reset in time, the system continues to record the previous data, causing the indicator light to illuminate. Simply performing a TPMS reset will resolve this issue. Damaged tire pressure sensor: The sensor, which monitors tire pressure, is directly installed inside the tire and connected to the inflation valve. If the sensor is damaged during driving (e.g., by hitting a curb), the tire pressure warning light will activate. Damaged sensors must be replaced with new components.
