What is the normal tire pressure for Buick Excelle?
2 Answers
The normal tire pressure range for the Buick Excelle 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 method to check the tire pressure in the Excelle is: press the menu button to switch to the vehicle information menu, rotate the knob at the top of the left lever to the tire pressure monitoring information interface, and you can see the tire pressure of all four wheels. Generally speaking, 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; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread of the tire, reducing tire lifespan; increased body vibration, indirectly affecting the lifespan of other components; excessive stretching of 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; causing heavy steering and deviation, which are unfavorable for driving safety; increased movement of various parts of the tire, leading to abnormal heating due to excessive rolling; reduced functionality of the cords and rubber, causing delamination or cord breakage and excessive friction with the rim, leading to damage and abnormal wear at the bead area; multiplied friction between the tire and the ground, sharply increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol, an irregular circle with no stamp on top and four small spikes at the bottom, with an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: usually alerts when below 1.8bar or above 3.0bar. At this time, 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 tire pressure monitoring system to still record the previous data, and the tire pressure monitoring indicator light will come on. At this time, simply perform a tire pressure reset. 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 during driving, it will also cause the tire pressure warning light to come on. For sensor damage issues, only a new replacement part can be used.
I always prioritize driving safety, and tire pressure is particularly crucial for the Buick Excelle. The recommended normal range is between 32 and 35 PSI, with the specific value indicated on the label on the driver's side door frame. If the tire pressure is too low, the tires are prone to overheating and blowouts; if the pressure is too high, traction weakens and braking distances increase. I make it a habit to check every two weeks, preferably using a tire pressure gauge when the car is cold, as driving heats up the tires and affects the readings. Seasonal changes also matter—in winter, a slightly higher pressure of 35 PSI is fine, while in summer, a slightly lower 32 PSI helps avoid bumps. During regular maintenance, the 4S shop can assist with adjustments, but doing it yourself is simple, convenient, and prevents problems before they arise. Never wait until an issue occurs to regret neglecting it.
