Science behind the design of Tire


From my childhood i thought that the Tire design is to have a good grip of vehicle to hold on the land. But how it happens i never knew till now...

So whats behind it?

Basically when a rotating body (surface) for example a tire, is kept on a fluid, due to the velocity at the tire surface, the fluid also gets dragged. In the process, there is lift produced which will make the tire float. For this not to happen, we need to remove the water from below the tire surface...which is done by the grooves, design of Tire.

The others things of the design shown here are basically for better strength, reliability etc.
