What is the appropriate tire pressure for a Toyota Highlander?
1 Answers
The normal tire pressure range for the 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 decreased by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard requirements. Some Highlander models are equipped with a tire pressure display function. There is a menu selection on the steering wheel; by pressing to the instantaneous fuel consumption display and then pressing the directional key downward, the tire pressure will be shown. The tire pressure monitoring system is a type of active safety device that can alert the driver in time when there are signs of danger in the tires, prompting the driver to take appropriate measures to avoid serious accidents. Generally speaking, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is considered 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 of the tire, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increases the 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, causing damage to the bead area and abnormal wear; multiplies the 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 below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure. Usually, it alerts when the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset. After inflating the tires, if the tire pressure is not reset in time, the system may still record the previous data, causing the indicator light to stay on. Simply perform a tire pressure reset to resolve this. Damaged tire pressure sensor. The tire pressure sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged due to impact while driving, the tire pressure warning light may illuminate. For sensor damage, the only solution is to replace it with a new one. For a Toyota Highlander, a tire pressure of around 2.4-2.5 bar is considered standard. Normal tire pressure reference standards: According to the international GBT2978-2008 standard, standard tires should have a pressure of around 2.4-2.5 bar, while reinforced tires should have around 2.8-2.9 bar. In winter, it is advisable to increase the tire pressure by about 0.2 bar based on the standard, while in summer, the pressure can be slightly lower by about 0.1 bar to avoid blowouts due to high temperatures. Daily tire pressure precautions: Most vehicles are equipped with a tire pressure monitoring system that alerts drivers to leaks and abnormal tire pressure to ensure driving safety. Pay attention to the tire pressure monitoring light on the dashboard; both underinflation and overinflation can affect driving performance and increase tire wear.
