The tire model specification for the Buick Excelle is 185/65R15. The first number, 185, indicates the tire width is 185MM. The number 65 represents the aspect ratio of the tire section, which is 65%, meaning the section height is 65% of the width. The letter R stands for radial tire, and 15 denotes the rim diameter is 15 inches. The Buick Excelle has a top speed of 170km/h and a fuel consumption of 4.7L per 100km. In addition to the model, the tire also displays the following common data: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent the certified speed ratings of the tire, ranging from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h.

I bought a used 2012 Buick Excelle last year and found its tire specification is 195/65 R15, a common configuration for older models – 195mm tread width, 65% aspect ratio, and 15-inch rims. It drives quite smoothly. However, my friend’s newer 2018 model comes with 205/55 R16 tires, slightly larger in size, offering better cornering stability but slightly higher fuel consumption. When replacing tires, don’t blindly buy the original factory specifications, as it may affect braking and handling, and could accelerate wear. Last month, I switched to Bridgestone’s economy tires, which have performed well over 5,000 km—quiet and fuel-efficient for daily city driving. I recommend checking tire pressure and tread depth every two years, as safety comes first. Before long trips, I always inspect the tires—wrong sizes are too dangerous, increasing the risk of blowouts or skidding on highways. Remember to confirm the exact specifications for your car’s model and year at a 4S store first to avoid wasting money and time.

Straight-line driving speed should be between 30 km/h and 40 km/h, meaning it should not be lower than 30 km/h or higher than 40 km/h. Below are some relevant techniques for straight-line driving: Selecting a reference point: When driving straight, the driver should look ahead and pay attention to both sides, choose a reference point, maintain straight-line driving, correct the direction in time, and always be aware of various traffic conditions ahead to detect and handle them promptly. Adjusting the viewing distance ahead in time: Look far and near while holding the steering wheel straight. The driver should adjust the viewing distance ahead according to the speed. At higher speeds, look further ahead; at lower speeds, look appropriately closer, and use peripheral vision to monitor the surroundings. Steering smoothly: Operate the steering wheel by pulling with one hand and pushing with the other, ensuring smooth control. Keep both hands shoulder-width apart and avoid using excessive force.
