Why more rubber on the road doesn't always mean better grip
In short: It seems counterintuitive: why would cutting into a tire improve its performance? This video explains the engineering behind tread patterns and how they manage the physics of driving in diverse conditions.
While a smooth surface provides more contact area, modern tires use grooves and channels to manage water. These patterns are essential for preventing hydroplaning by allowing water to be displaced from under the tire, ensuring the rubber maintains traction with the road.
The video also explores the trade-offs in high-performance scenarios, such as why racing cars utilize completely smooth tires while everyday vehicles require complex treads for handling and safety.
