What is the normal tire pressure for the Buick Verano?
2 Answers
The normal tire pressure range for the Verano 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 complies with 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 tire pressure gauge against the tire valve to measure and read the value. Remember to replace the valve cap after measuring. Generally, a tire pressure above 2.8 bar is considered too high, and below 2.0 bar is 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 pattern, 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 friction with the road surface, raising fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement of tire components, causing abnormal heat due to excessive rolling; degrades the function of 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 with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a 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), there are generally three possible reasons: Abnormal tire pressure: Typically, an alert is triggered 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, if the tire pressure is not reset in time, the system will still record the previous data, causing the indicator light to stay on. Simply perform a tire pressure reset. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged during driving (e.g., by impact), the tire pressure warning light will illuminate. A damaged sensor must be replaced with a new one.
I've been driving a Buick Verano for several years, and in daily driving, I've found that maintaining tire pressure between 32 to 35 psi is ideal, which is equivalent to about 2.2 to 2.4 bar. The recommended values are detailed on the sticker inside the driver's door frame or in the user manual. I check the tire pressure regularly, especially during seasonal changes. In winter, when temperatures drop, tire pressure tends to decrease, so it's necessary to add some air appropriately. Incorrect tire pressure can accelerate tire wear, increase fuel consumption, and cause noticeable shaking when driving on highways, which is very unsafe. It's best to measure tire pressure in the morning when the tires are cold. I always use a simple tire pressure gauge to do it myself—it's easy and reassuring. Remember, the correct tire pressure ensures smoother driving and reduces unnecessary maintenance costs.
