What is the normal tire pressure for the 2021 Corolla?
1 Answers
The normal tire pressure range for the 2021 Corolla is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and reduced by 0.1bar in summer. This data is based on the international GBT2978-2008 standard. To check the tire pressure in the 2021 Corolla, use the buttons on the left side of the steering wheel to toggle left and right. First, press the left button on the steering wheel to toggle, and then you can see the tire pressure numbers for all four wheels displayed on the right side of the instrument panel. Generally, a tire pressure above 2.8bar is considered too high, and a tire pressure below 2.0bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates localized wear on the central tread of the tire, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends the 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; 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; reduces the functionality of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing 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 result in a tire blowout. 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), it is generally due to one of the following three reasons: Abnormal tire pressure: Typically, it will alert if the pressure is below 1.8bar or above 3.0bar. In this case, a tire inspection and pressure adjustment are needed. 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 indicator light to come on. 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 valve. If the sensor is damaged due to impact while driving, it will also trigger the tire pressure warning light. For sensor damage, the only solution is to replace it with a new one.
