Fractional sizes in auto refer to the measurements of tire dimensions, specifically the width, aspect ratio, and diameter, expressed in inches or millimeters. For example, a tire size like 215/60R16 indicates a tire width of 215 mm, an aspect ratio of 60% (height to width), and a diameter of 16 inches. These sizes help ensure that tires fit correctly on vehicles and maintain optimal performance and safety. Understanding fractional sizes is crucial for selecting the right tires for specific vehicles.
