Aspect ratio on a tire measures the sidewall height as a percentage of the tire’s width. For instance, a 70% aspect ratio means the sidewall height is 70% of the width. A higher aspect ratio results in a taller sidewall, which affects ride comfort and handling. Knowing the aspect ratio assists in choosing the right tire measurements.
The aspect ratio significantly influences a tire’s performance. Tires with a low aspect ratio often provide better handling and cornering due to their wider stance and stiffer sidewalls. They tend to have enhanced stability at high speeds. However, they may sacrifice ride comfort and can be more susceptible to damage from road imperfections.
Conversely, tires with a high aspect ratio generally offer a smoother ride. This is because their taller sidewalls can absorb shocks more effectively. They are advantageous for off-road conditions but may compromise cornering performance on paved roads.
Understanding aspect ratio is essential for selecting the right tire for specific driving needs. Therefore, choosing a tire involves balancing between performance preferences and comfort requirements. In the next section, we will explore how aspect ratio impacts tread design and its implications for traction and durability.
