Aspect ratio on a tire is the ratio of the tire's height to its width. It is expressed as a percentage and is found on the tire's sidewall, usually following the tire width in the sequence. For example, in the tire size 225/50R16, '50' is the aspect ratio, meaning the height is 50% of the tire's width. Understanding aspect ratio helps in selecting tires that provide a balance of comfort, performance, and appearance.
