The ancient Mesopotamians invented the wheel originally in the form of a potter’s wheel. It developed into a solid wooden disk with a hole in the middle for an axle. To make the wheel lighter and more practical the spoked wheel was developed. The [[Greece|Greeks]] used this type of spoked wheel. The [[Celts]] introduced a [[bronze]] rim around the outside of the wood to strengthen the structure. That was how the wheel remained, without major modifications, until the [[19th century|1800’s]] when modern rubber tires started being developed.

In 1845, Robert William Thomson patented the pneumatic tire in [[England]]. Pneumatic means that the tire was filled with air to provide a "...cushion of air to the ground." This type of tire was originally used on bikes but soon moved on to the automotive world. To this day, pneumatic tires are used on bikes and [[Automobile|automobiles]].

In 1845, Scotsman Robert William Thomson patented the vulcanized rubber pneumatic tire in [[Scotland]]. Pneumatic means the tire is made from reinforced rubber and filled with air to provide a "...cushion of air to the ground." This type of tire was originally used on bikes but soon moved on to the automotive world. To this day, pneumatic tires are used on bikes and [[Automobile|automobiles]].
