Do Car Tires Have Inner and Outer Tires?

[EleanorLee]

Most car tires do not have outer tires. Here is relevant information: 1. Types of Tires: Inflatable tires can be divided into two types based on their structure: tubed tires and tubeless tires. Passenger cars commonly use tubeless tires. Based on the arrangement of internal cord layers and buffer layers, tires can also be classified into radial tires and bias tires. Radial tires are widely used in vehicles. The sidewalls of tires are marked accordingly. 2. Function of Tires: Tires are in direct contact with the road surface and, together with the car suspension, help to cushion the impact during driving, ensuring good ride comfort and smoothness. They also ensure good adhesion between the wheels and the road surface, improving the car's traction, braking, and off-road capability. Additionally, tires bear the weight of the car.
