What is the normal tire pressure for a Highlander?
1 Answers
The normal tire pressure range for a Highlander 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. Most Highlander models are equipped with a tire pressure display function. There is a menu option on the steering wheel. After finding the instant fuel consumption, pressing the down arrow key will display the specific tire pressure value. 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 excessive tire pressure: The friction and adhesion of the tire will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear of the tread pattern in the center of the tire, reducing tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; it can cause excessive stretching and deformation of the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving. Hazards of insufficient tire pressure: The friction coefficient with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, which are factors detrimental to driving safety; it increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; it reduces the functionality of the cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; the friction between the tire and the ground increases exponentially, rapidly raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under such conditions may lead to 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 below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, 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, 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 is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the sensor is damaged due to impact while driving, it can also cause the tire pressure warning light to come on. For sensor damage issues, only replacement with a new part is possible.
