A » The tire size designation, such as P215/65R15, indicates its width, aspect ratio, and diameter, affecting performance. A wider tire (215 mm) offers better traction and stability, while the aspect ratio (65) impacts ride comfort and handling. The R signifies radial construction, common for durability, and the 15 denotes the wheel diameter, influencing speedometer accuracy and braking. Together, these factors determine performance, handling, and fuel efficiency.
