Tires may not seem as important as a motor or a transmission. However, tires are crucial when riding, especially while racing!

Tires are used for grip and the tires need traction is very important to the overall riding experience.

Gripping the road, the track, the dirt, or whatever terrain you may be on. 

Tires are also important for turning and leaning. 

When you lean you want to make sure your tires have enough grip to not let the bike slide from under you. Even when riding straight up, if the tire has no traction, you will be doing more spinning than it gripping and rolling.
