2 Answers
The model and specification of the Buick Excelle tire is 185/65R15. The first number, 185, represents the tire width of 185MM. 65 indicates the aspect ratio of the tire section is 65%, meaning the section height is 65% of the width. The letter R stands for radial tire, and 15 represents the rim diameter of 15 inches. The Buick Excelle has a maximum speed of 170km/h and a fuel consumption of 4.7L per 100km. In addition to the model, the tire also carries the following common data: Tire cord material: Indicated by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-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 from 4.8km/h to 300km/h. Commonly used speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Indicates the rim specification compatible with the tire for practical use, such as "Standard rim 5.00F".
I remember last year when I took my Buick Excelle to change tires, the mechanic immediately pointed out that the original factory tires are usually 195/65 R15 or 195/55 R16, depending on the model year. For example, older models before 2010 mostly used 195/65 R15, while newer models might have been upgraded to 16-inch. These specifications mean the tire width is 195 millimeters, the height is 65% of the width, and the tire diameter is 15 inches. When changing tires, it's essential to match the manufacturer's recommendations to maintain stable steering and braking. From my own experience, if you accidentally install the wrong size, fuel consumption will increase, and it's easier to skid in rainy weather. So, I recommend everyone to regularly check the label on the door edge or the vehicle manual, where the accurate model information is indicated. When replacing, consider well-known brands like Michelin or Continental for longer lifespan. Generally, tires should be replaced every 5 years or when the tread wears down to the safety line. Don't compromise safety to save a little money.
