What is the introduction to tire sizes?

[NicoleMarie]

Generally, base model cars use tires that are one size smaller, but the aspect ratio of the tires will also increase, resulting in minimal overall difference. High-end models use larger tires, which increase ground clearance and improve comfort, but there is no significant difference in handling. Introduction 1: Tires are the main components of a car during operation, and their performance directly affects the vehicle's safety, stability, and fuel efficiency. Nowadays, radial tires are commonly used in cars. The tire cord layers are arranged parallel to each other, resembling the meridians of the Earth, hence the name radial tires. Introduction 2: Compared to conventional bias-ply tires, radial tires are characterized by greater elasticity, better wear resistance, which can extend tire life by 30% to 50%, lower rolling resistance, reducing fuel consumption by about 8%, and superior traction, cushioning performance, and load capacity. Therefore, the use of radial tires is becoming increasingly widespread.
