Infiniti Q45 Tire Sizes & Rim Dimensions by Year and Trim

The Infiniti Q45 offers a range of tire sizes and rim dimensions that vary depending on the model year and trim level. Generally, the tire specifications balance performance and comfort, reflecting the vehicle's luxury sedan status.\n\nCommon tire sizes for earlier Q45 models typically include 225/55R16, with rim widths ranging from 7 to 7.5 inches and diameters around 16 inches. Later trims and higher-performance versions move towards wider tires such as 235/55R16 or larger diameters like 17 inches, often paired with rim widths up to 8 inches.\n\nWhen comparing trims, it is essential to verify both tire sidewall markings and rim dimensions, as upgrades or sport packages often increase rim diameter or width to improve handling characteristics. Understanding these differences aids in selecting replacement tires or aftermarket wheels that maintain proper fitment and vehicle dynamics.\n\nAlways consult your vehicle's manual or a trusted tire professional to confirm tire and rim specifications compatible with your Infiniti Q45's year and trim, ensuring safety and optimal performance.
