Here are the reasons why tires of cars are threaded:
1. Enhanced Traction: The tread pattern increases the tire's contact area with the road, allowing it to grip better. This is crucial for accelerating, braking, and cornering, as it helps maintain control of the vehicle.
2. Water Dispersion: Designed with grooves called "channels," the tread helps evacuate water from beneath the tire during wet conditions. This prevents hydroplaning, where the tire loses contact with the road due to a layer of water, which can lead to loss of control.
3. Noise Reduction: The specific design and spacing of tread blocks help reduce road noise. The grooves and patterns act as sound dampeners, absorbing and dispersing the sound energy created by the contact of the tire with the road.
4. Reduced Wear: The tread pattern ensures even wear and tear across the tire's surface, extending its lifespan. By reducing the concentrated pressure on specific spots, the tread design promotes uniform contact between the tire and the road.
5. Improved Handling: Threaded tires provide better handling and stability to vehicles. The pattern allows the tire to respond efficiently to changes in direction and absorb irregularities in the road, enhancing overall driving control.
6. All-Weather Performance: Different tread patterns are designed for specific weather conditions. Certain tread designs, like those with deeper grooves and sipes, enhance grip in snow and icy conditions, while others are better suited for dry and warm road surfaces.
In addition to these primary functions, the tread design also helps in aesthetics and gives a unique identity to different tire models and manufacturers.
