What are types of wheels?
The Different Types of Wheels
- Alloy Wheels. Alloy wheels are the most common on the market.
- Steel Wheels. Steel wheels cost less than the other kinds.
- Forged and Cast Wheels. To make steel or alloy wheels, manufacturers have two options available to them: casting or forging them.
- Split Rim Wheels.
Why wheels are so useful?
Wheels are important because they are used for transportation. Heavy machines can be moved from one place to another with the help of wheels because wheels can be rolled and the amount of force is also comparatively less.
What are wheels made of?
The majority of wheels today are cast aluminum alloy, meaning they’re made by pouring molten aluminum into a mold.
Why is the wheel important?
Without it, things would be really different. Wheels can be used for transportation. For example, before the wheel was invented, people had to walk, carry very heavy things, and had to use a boat to get over seas. Now we have cars, bicycles, wagons, dollies and airplanes!

How was wheel invented?
The wheel was invented in the 4th millennium BC in Lower Mesopotamia(modern-day Iraq), where the Sumerian people inserted rotating axles into solid discs of wood. It was only in 2000 BC that the discs began to be hollowed out to make a lighter wheel. This innovation led to major advances in two main areas.
How did the wheel make life easier?
Since its invention, the wheel has been used extensively and improved upon throughout the history. Archaeological evidence from the palaeolithic era – around 750,000 years ago – suggests that early humans knew that heavy objects could be moved easily by rolling them.
