Infiniti EX Tire Sizes & Rim Dimensions by Model Year and Trim
The Infiniti EX offers a range of tire sizes and rim dimensions that vary by model year and trim level. Typically, the rim widths range from 7 to 8 inches with diameters commonly between 17 and 19 inches. These variations impact both the vehicle's handling and ride comfort.\n\nFor example, base trims usually come with smaller wheels, such as 17x7 inches, while higher trims often feature larger 19x8 inch rims paired with low-profile tires for enhanced performance. Comparing trims involves checking the stamped tire size markings on the sidewall, which indicate width, aspect ratio, and diameter (e.g., 235/55R17).\n\nUnderstanding these markings helps ensure compatibility when replacing tires or upgrading rims. Always cross-reference model year and trim to select tires and wheels that match factory specifications or desired performance characteristics. This ensures safety, optimal driving dynamics, and proper fitment.
