Soon after auto racing began, engineers realized that getting more rubber on the road was one way of increasing cornering speeds. One of the more interesting early attempts to get more rubber on the road was by running dual rear tires. However, the more typical solution was the use of tires with wider tread and section width. This was the first of numerous steps toward lower tire aspect ratios. Since then, due to ever-increasing vehicle handling requirements and the existence of trends to high performance tires, passenger car tire aspect ratios have been decreased. Today, racing tire aspect ratios have gone as low as 0.25.
Tire aspect ratio is defined as tire ...
