What is the tire model of the BMW X3?
2 Answers
The tire model of the BMW X3 is 245/50R19. The first number, 245, represents the tire width of 245MM. The 50 indicates that the tire's aspect ratio is 50%, meaning the section height is 50% of the width. The letter R stands for radial tire, and 19 represents the rim diameter of 19 inches. The BMW X3 has a top speed of 250km/h, accelerates from 0 to 100km/h in 4.72 seconds, and has a fuel consumption of 8.3L 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 specified 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. Rim specification: Indicates the rim size compatible with the tire for practical use, such as "Standard rim 5.00F".
I remember the BMW X3 typically uses tire sizes like 245/50 R18 or 245/45 R19, depending on configurations such as model year and drivetrain. The sDrive versions may have slightly smaller tires, while xDrive models often come with larger ones. From my repair experience, many people mistakenly assume all X3s use the same tires, but tires significantly impact handling and safety—I recommend checking the door jamb sticker or manual to confirm the exact size. When switching to winter tires, it's crucial to match the original dimensions; otherwise, you'll compromise comfort and fuel efficiency. Regularly checking tire pressure also helps extend their lifespan. In short, don’t rely solely on online guesses—verify the details yourself for accuracy.
