The original tire configuration model for the Infiniti QX50 is 235/55/R19. The first number 235 indicates that the tire width is 235MM, 55 represents the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width. The letter R stands for radial tire, and 19 denotes the rim diameter is 19 inches. The Infiniti QX50 has a fuel consumption of 7.7L per 100 kilometers. In addition to the model, the tire also displays the following commonly used data: Tire cord material: Represented 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 the certified speed ratings of the tire 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: Shows the rim specification compatible with the tire for practical use, such as standard rim 5.00F.
I remember when I drove the Infiniti QX50, the tire size was usually 235/55R19, which was the standard configuration used for most models. However, specific years and trims might vary—for example, the base 2020 model came with this size, while higher trims might use 255/45R20. From my personal experience, the tires on this car provide a comfortable ride, with low noise on highways and decent wet traction. I’d advise fellow drivers to check the label on the door frame to confirm the exact size rather than relying on memory. When replacing tires, make sure to choose the correct size and avoid cheap off-brand options to maintain balance and safety. During my last maintenance, I reminded the technician to check tire pressure and wear since tires are crucial for driving stability. Overall, the QX50 is designed for family use, and this tire size pairs well with its suspension. For city driving, 235-width tires are sufficient, but for off-roading, you might need to consider upgrades or modifications.
