What to Do When the Left Rear Tire of an Audi Has Insufficient Pressure?

[VanStella]

Audi Q3 tire pressure is insufficient. First, check if the tire pressure is adequate. If it is insufficient, it needs to be replenished. After inflating, you can reset it via the MMI settings. Press the car button and select 'Store Tire Pressure' to proceed. If the TPMS light on the dashboard is on, a system upgrade at a 4S shop is required. The standard tire pressure for an Audi Q3 is around 2.5, with a normal fluctuation range of ±0.2. The hazards of excessive tire pressure are as follows: 1. Tire damage: Reduced friction and adhesion of the tire, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort. 2. Accelerated tire wear: Accelerates localized wear of the tread pattern in the center of the tire, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components. 3. Accelerated tire deformation: Causes excessive stretching and deformation of the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving. 4. Performance degradation: When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, leading to internal cracks and blowouts, resulting in a tire burst.
