Increasing Friction
Treaded tires are designed with grooves and patterns on the surface of the tire, which help in increasing friction between the tire and the road surface. This increased friction allows the tire to have better grip on the road, especially in wet or slippery conditions. The tread patterns help channel water away from the tire, preventing hydroplaning and improving overall traction.

Increasing Longevity
The tread on tires also helps in increasing the longevity of the tire. As the tire rolls on the road, the tread gradually wears down. The tread patterns are designed to wear down evenly, ensuring that the tire maintains good traction and performance throughout its lifespan. Without tread, the tire would wear down unevenly, leading to reduced performance and safety.

Visual Appeal
Treaded tires are also treaded to enhance the visual appeal of the vehicle. The patterns and designs on the tread can vary, providing a customized look to the vehicle. Additionally, the tread can add a sporty or rugged appearance to the tire, depending on the design. This visual appeal can enhance the overall aesthetics of the vehicle.
In conclusion, treaded tires are not only designed to look good, but also serve important functional purposes such as increasing friction, improving longevity, and enhancing the visual appeal of the vehicle.
