What does the tire tread do? On a normal, smooth road, the tread has only limited influence on the riding properties. The grip generated by the tire on the road is almost exclusively the result of the rubber compound. Unlike a car, a bicycle will not aquaplane. The contact area is much smaller and the contact pressure is much higher.
NASCAR tires do not have tread because the cars do not drive on a wet surface. Tread helps channel water away from the surface of the point where the rubber meets the road. Siâ¦nce NASCAR does not race in the rain, a smooth tire gives more surface for the tire for the most traction and speed. 4 people found this useful.
