What is the appropriate tire pressure for the 2021 Buick Excelle?
2 Answers
The normal tire pressure range for the 2021 Buick Excelle 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 requirements. Method to check tire pressure for the 2021 Buick Excelle: Press the MENU button to switch to the vehicle information menu. If a speeding alarm is displayed, rotate the knob at the top of the left lever to the tire pressure monitoring information to view the pressure of all four tires. Generally, a tire pressure above 2.8 bar is considered too high, while a pressure below 2.0 bar is too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, 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 underinflated tires: 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 functionality, leading to delamination or cord breakage, excessive friction with the rim, and damage to the bead area, 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 seal 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 1.8 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, failure to reset the tire pressure monitoring system results in the system retaining old data, causing the indicator to light up. Simply reset the tire pressure to resolve this. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If damaged during driving, it triggers the tire pressure warning light. A damaged sensor must be replaced with a new one.
I just bought a Buick Excelle 2021 model, and the manual recommends a tire pressure of 32-35 PSI. I usually inflate them to around 33, which works perfectly. The car drives comfortably with low fuel consumption and no bumpiness. I always remind myself to check the tire pressure once a month using a simple tire pressure gauge—many gas stations now offer free services. If the tire pressure is too low, the tires wear out faster and consume more fuel; if it's too high, handling becomes unstable. By the way, Buick has a label sticker on the driver's side door frame listing the specific values for easy reference. Safety first—before long trips, I’ve made it a habit to check. Overall, keeping it within the 32-35 range is the most hassle-free. Don’t exceed 40 or go below 30. I’ve personally experienced this a few times, and adjusting it noticeably improved the driving feel. It also extends tire life, saving money and effort—why not?
