Pneus, commonly known as tires, are rubber coverings that fit around the wheels of vehicles. They provide traction, support the weight of the vehicle, and help absorb shocks from the road. Pneus come in various types, including all-season, winter, and performance tires, each designed for specific driving conditions. The construction of pneus typically includes layers of rubber, fabric, and steel belts, which enhance durability and performance. Proper maintenance, such as regular inflation and alignment checks, is essential for safety and efficiency. Worn or damaged pneus can lead to reduced handling and increased risk of accidents.
