thousands of years later, the wheel has come a long way. for one thing it is no longer made of wood and it is guaranteed that the ride is much smoother. what hasn't changed is the fact that it is still one of man's greatest inventions. could you imagine where we would be today without it?

the early wheel was very simple: a solid curved piece of wood. later, leather was added to soften the ride. as time progressed it became solid rubber which led to today's tire--the pneumatic, or air inflated, radial tire.

the first wheels made of metal or wood were very durable but did not provide a very comfortable ride. the nearest thing to the first tire was a metal hoop. there were many individuals that made contributions in creating the tire as we think of it today.
