Pneumatic tyres are inflatable rubber coverings that provide a cushion of air between the vehicle and the road. They are designed to improve traction, handling, and comfort while driving. The air inside the tyre helps absorb shocks from bumps and irregularities on the road, making for a smoother ride. These tyres are commonly used on various vehicles, including cars, bicycles, and trucks. The construction typically includes layers of fabric and steel belts, which enhance strength and durability. Proper inflation is crucial for optimal performance and safety, as under-inflated tyres can lead to increased wear and reduced fuel efficiency.
