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.
Understand that the primary function of tread on a tire is to divert water from beneath the tire to improve traction and avoid hydroplaning on wet roads. Tires become unsafe when they're worn, and once the tread is down to 1/16th of an inch (1.6mm), the tire is no longer safe. 2. Look at the tread pattern.
