How to Calculate Aspect Ratio?
1 Answers
Aspect ratio refers to the percentage of a tire's section height relative to its maximum section width. Below is relevant information about aspect ratio: 1. Introduction: The tire section consists of the shoulder, sidewall, and bead. The sum of their heights constitutes the tire section height. After installation, since the bead is hidden within the rim, the measured height from the rim to the outer section (tread) is slightly less than the tire section height. 2. Characteristics: Tires with a high aspect ratio have longer sidewalls, providing stronger cushioning and relatively higher comfort, but they offer poorer road feedback and weaker lateral resistance during turns. Conversely, tires with a low aspect ratio and large inner diameter have shorter sidewalls and wider treads, resulting in a larger contact area and greater pressure-bearing capacity. They are highly responsive to road conditions, exhibit strong lateral resistance during turns, and enhance vehicle handling. After equipping a vehicle with wide, large-diameter, low-aspect-ratio tires, besides improved handling, the visual effect also gives a more aggressive appearance.
