What is the normal tire pressure for the Buick Verano?
1 Answers
The normal tire pressure range for the Verano 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. The Verano's tire pressure monitoring system is indirect, utilizing the vehicle's ABS balance control, and only displays low pressure when there is a leak. To check the tire pressure, first prepare a tire pressure gauge, locate the position of the factory tire pressure label, press the gauge onto the tire valve to measure and read the value, and remember to replace the valve cap after checking. Generally, a tire pressure above 2.8bar is considered too high, and below 2.0bar is too low. Hazards of over-inflation: 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 under-inflation: 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; weakens cord and rubber functions, 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 ground, sharply raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a blowout. If the tire pressure monitoring indicator lights up (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: Typically alerts when pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, the system wasn't reset, so it still records the previous data, causing the indicator to light up. Simply reset the tire pressure monitoring. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If damaged during driving (e.g., by impact), the tire pressure warning light will activate. A damaged sensor must be replaced with a new one.
