What Does Tire Section Width Mean?

[JakeFitz]

When conducting a cross-sectional analysis of a tire, it is necessary to cut the tire open. The distance between the two sidewalls after the cut is referred to as the tire section width. Below are specific details about tires: Composition: Tire specifications include the tire section width, aspect ratio, load index, speed rating, tire type, and applicable rim diameter. Among these, the tire section width significantly impacts tire safety, and it refers to the width of the tire's cross-section. Impact: Tires with a larger section width naturally have a greater contact area with the ground. During driving, this increases the friction between the tire and the road surface. Not only does this enhance the tire's wet traction performance, but it also improves water drainage, thereby increasing driving safety in rainy conditions.
