A pneumatic tire is a type of tire that is inflated with air, providing a cushion of air between the tire and the road. This design helps absorb shocks and improves ride comfort, making it ideal for vehicles like cars, bicycles, and trucks. The air pressure within the tire also helps maintain its shape and provides traction on various surfaces. Pneumatic tires are typically made from rubber and may include layers of fabric and steel for added strength. They come in various sizes and tread patterns, which can affect performance, handling, and durability. Proper inflation is essential for safety and efficiency.
