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.
Today most tires are pneumatic tires, though typically still referred to as just tires. The word pneumatic simply means an item that uses air. Tires work because they have tread on them. Tread is the raised patterns that appear on the top of a new tire, which often appear to zigzag around the tire. The tread helps the tire gain traction on the road to prevent it from sliding.
