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.
What Is a Bald Tire? The part of a tire that contacts the road is called the tread, and this tread wears down over time. When a tire's tread is completely worn down to the wear bars, you have a bald tire. And if your vehicle has bald tires, you need new tires right away-driving on bald tires is not safe.
