What does the aspect ratio of a tire mean?

[LaSara]

Aspect ratio is a data point in tire specifications, referring to the percentage of the tire's section height to its maximum section width. Simply put, it is the height-to-width ratio of the tire. It usually appears on the tire sidewall in a format like 205/60R15, where the 60 represents an aspect ratio of 60%, 205 indicates a tire width of 205mm, R stands for radial construction, and 15 denotes a rim diameter of 15 inches. Additional information: 1. Both high and low aspect ratios have their advantages: a high aspect ratio offers better comfort, while a low aspect ratio provides better handling. Tires with a high aspect ratio have longer sidewalls, offering stronger cushioning and relatively higher comfort, but they provide poorer feedback on road conditions and weaker lateral resistance during turns. 2. Tires with a low aspect ratio have shorter sidewalls: the tread is wider, and the tire can withstand greater pressure, offering more responsive road feedback and better handling. Additionally, low-aspect-ratio tires provide a more striking visual impact, enhancing the overall premium feel of the vehicle.
