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.
1 In steel-belted radial tires, belts made from steel are used to reinforce the area under the tread. 2  These belts provide puncture resistance and help the tire stay flat so that it makes the best contact with the road. 3  Some tires have cap plies, an extra layer or two of polyester fabric to help hold everything in place. The tread is made from a mixture of many different kinds of natural and synthetic rubbers. 2  The tread and the sidewalls are extruded and cut to length. 3  The tread is just smooth rubber at this point; it does not have the tread patterns that give the tire traction.
