How to Read Tire Width?

[VonCollin]

Tire model markings are mostly in the form of: 215/70R15. The meanings of these numbers are as follows: 215 indicates the tire section width in millimeters, with general tire widths ranging between 145—285mm, in increments of 10mm; 70 is the aspect ratio, representing the ratio of the tire sidewall height to the tire section width, where 70 stands for 70%. Generally, tire aspect ratios range between 30%—80%. Relevant information about tubeless tires is as follows: 1. Introduction: Tubeless tires, also known as 'low-pressure tires' or 'pneumatic tires,' have high elasticity and wear resistance, along with good adhesion and heat dissipation performance. Particularly, all-steel radial tubeless tires are economical and durable. 2. Application Scope: In recent years, tubeless tires have been increasingly used in bicycles, motorcycles, cars, buses, and trucks.
