What is the structure of a tire?

Tire structure is composed of the tread, shoulder, sidewall, bead, carcass, belt layer, inner liner, and other components combined together. Below is some related extended information: 1. Tire: The tire is one of the important components of a car. It directly contacts the road surface and works together with the car suspension to cushion the impact during driving, ensuring good ride comfort and smooth driving. 2. Tire classification: Tires can be classified by structure into radial tires and bias tires. By tread pattern, they can be categorized into rib pattern tires, transverse pattern tires, mixed pattern tires, and off-road pattern tires. By type, they can be roughly divided into 8 categories. By size, full-size spare tires: Full-size spare tires have exactly the same specifications as the other four tires on the car and can replace any temporarily or permanently unusable tire. Non-full-size spare tires: These spare tires have slightly smaller diameter and width compared to the other four tires, so they can only be used as a temporary replacement and must be used on non-driving wheels, with a maximum speed not exceeding 80 km/h.
I've been fascinated by cars since childhood and often played with disassembling and assembling tires. The structure of a tire is actually quite interesting: the outermost part is the tread, which has various patterns, like the grooves on the tread, providing grip and preventing skidding, ensuring no slipping even in rainy weather; the middle part is the sidewall, which feels quite soft and absorbs road bumps, reducing interior noise; hidden inside are several layers, such as the ply layer, made of sturdy materials, acting like the skeleton of the tire to maintain shape stability; the bottom part is the bead, which tightly secures the wheel rim to prevent air pressure from leaking. This multi-layer design allows the tire to withstand heavy pressure and reduces wear. When driving, it's important to maintain proper tire pressure and avoid sidewall scratches, as these can lead to tire blowouts and compromise safety. Regularly check the tread depth—if it's too shallow, it's time to replace the tire, saving money and ensuring peace of mind.
I've only been driving for a little over a year, but after delving deeper into tires, I find their structure incredibly practical: the tread is the key part that directly contacts the road, with the depth of the tread pattern affecting braking performance and noise levels; the sidewall is the tire's lateral part, softer to cushion vibrations and enhance comfort; inside, there are reinforcement layers, such as some metal or fiber woven materials, to increase strength and prevent deformation; the bead part connects to the wheel, where sealing is crucial. The entire vehicle relies on it for support, and if there's internal wear or unevenness, it can lead to dangerous skidding. During routine maintenance, I check the sidewalls for cracks and ensure the tire pressure is correct, which helps extend the tire's lifespan and can even save on fuel costs.
