LEXUS IS Tire Sizes and Rim Dimensions by Model Year and Trim

The LEXUS IS line features varying tire size markings depending on the model year and trim level. Understanding these markings is essential for selecting the correct replacement tires and rims.\n\nMost LEXUS IS models use rims ranging from 17 to 19 inches in diameter, with width variations typically between 7 to 8.5 inches. Tire markings such as 225/45R17 or 235/40R18 indicate the tire width, aspect ratio, and rim diameter suiting each trim.\n\nWhen comparing trims, consider that sportier trims often come equipped with wider and lower-profile tires for enhanced handling, while base trims use narrower tires prioritizing comfort. Always verify tire and rim sizes against your specific model year for optimal fit and performance.
