Pneumatic wheels are tires that are filled with air, providing a cushioning effect that enhances ride comfort and traction. They are commonly used in vehicles like bicycles, cars, and trucks, as well as in equipment such as hand trucks and lawn mowers. The air inside the tire allows it to absorb shocks from uneven surfaces, making it easier to navigate rough terrain. These wheels come in various sizes and designs, tailored for specific applications. The flexibility of pneumatic wheels helps improve stability and control, especially when turning or braking. Proper inflation is essential for optimal performance, as under-inflated tires can lead to increased wear and reduced efficiency.
