The semi-truck is an iconic vehicle seen on roads all around the world, but why is it called an 18 Wheeler? As it turns out, the name has to do with the number of tires it has.
The semi-truck is made up of two parts: a tractor and a trailer. The tractor is the front part with the engine, cab, and wheels.
The trailer is the long section behind it that carries cargo. Together, they make up what is known as an 18-wheeler due to its 18 tires.
The front part of the truck has six tires in total – two on each side of the axle and two in front – while the trailer has twelve. This adds up to eighteen in total, hence why they are referred to as 18-wheelers.
The semi-truck is a powerful vehicle capable of hauling heavy loads over long distances. This makes them ideal for transporting goods across countries and continents. They may be large and intimidating but they are essential for keeping our economy running smoothly.
Conclusion
In conclusion, the semi-truck is called an 18 Wheeler because it has eighteen tires – six in the front part (the tractor) and twelve in the back part (the trailer). These vehicles are important for keeping our economy running by transporting goods over long distances. Without them, many businesses would struggle to survive.
