What is the Lexus tire model?
2 Answers
Lexus tire configurations come in two models: 215/55R17 and 235/40R19. The first number, 215, indicates the tire width is 215MM. The 55 represents the aspect ratio of the tire's cross-section at 55%, meaning the section height is 55% of the width. The letter R stands for radial tire, and 17 denotes the rim diameter is 17 inches. The maximum speed of Lexus is 205km/h. In addition to the model, tires are also marked with 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: Shows the rim size compatible with the tire for practical use, such as standard rim 5.00F.
Lexus tire models are not uniformly fixed; different models or even the same model with different configurations may use different tires. Take my own ES300h for example, it came with Bridgestone tires in the size 235/45 R18, while my friend's RX450h is equipped with Dunlop tires in 235/55 R20. If you drive a large SUV like the LX570, you might use a wider and thicker size like 285/50 R20. The easiest way to find your tire model is to crouch down and look at the sidewall engraving—that string of characters resembling 'P245/50 R19' is definitely correct. Never cheap out and switch to a random model, as the wrong size can affect steering and braking performance. I once tried using a spare tire of the wrong model and felt the steering wheel become unstable.
