Aspect Ratio
The aspect ratio of a tyre is the ratio of its sidewall height to its width, expressed as a percentage. For example, in a 205/55R16 tyre, the aspect ratio is 55, meaning the sidewall height is 55% of the tyre's width (205mm). Lower aspect ratios generally indicate a sportier, more responsive ride, while higher aspect ratios offer more comfort and better protection against road damage.
