What is the tire model for the Buick Envision?
3 Answers
The Buick Envision has two tire models: 245/45R20 and 235/55R18. The first number 245 indicates the tire width is 245MM, 45 represents the aspect ratio of the tire section is 45%, meaning the section height is 45% of the width, and 20 indicates the rim diameter is 20 inches. The middle letters or symbols have special meanings: "X" denotes a high-pressure tire; "R" and "Z" denote radial tires; "-" denotes a low-pressure tire. The maximum speed is 210km/h, 0-100km/h acceleration is 8.0 seconds, and fuel consumption is 7.6L 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-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 A to Z represent certified speed ratings 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. Rim specification: Indicates the rim specification compatible with the tire for practical use, such as standard rim 5.00F.
The Buick Envision uses different tire models across its various configurations. The most common size is 225/65 R17, with a tread width of 225 millimeters, an aspect ratio of 65%, and 17-inch wheels, emphasizing economy and practicality, which is used in many mid to low-end models. If you see larger tires like 235/55 R19, they are typically installed on high-end models, with a tread width increased by 10 millimeters and wheels upgraded to 19 inches, providing noticeably better stability when driving. When purchasing a new car, the salesperson will usually inform you of the specific configuration, and you can also check the user manual for confirmation. If you're unsure, the most straightforward method is to crouch down and look at the raised numerical markings on the side of the tire—those starting with numbers like 225 or 235 are accurate. Of course, after changing tires, the tire pressure monitoring system needs to be recalibrated; otherwise, the system might give false alarms.
I frequently work with the Envision, and there are two key points to consider regarding its tire specifications. First is the wheel size: 17-inch wheels use 225/65 R17 tires, while 19-inch wheels are paired with 235/55 R19 tires—the wheel size directly determines the tire height. Second is the tire category: factory-installed options commonly include Goodyear's EfficientGrip and Continental's UC6, both positioned as quiet and comfortable. When replacing tires yourself, make sure to verify the exact model, or the wheel covers might not fit. There have been cases of older Envision models upgrading from 17-inch to 19-inch wheels, but this requires replacing both the wheels and tires as a complete set. The newer Envision Plus now offers some variants with massive 265/45 R21 tires, though those are exclusive to the top trim. Remember to get a wheel alignment every 20,000 to 30,000 kilometers—otherwise, uneven wear will shorten tire life.
