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.
Your tires should have tread at least 1/16 of an inch deep. If you live in a place where the roads are wet, icy, or otherwise slick, then your tread should be at least twice that. Over time, friction between the road and your tires start to wear on the tread.
