18 = Wheels on a Semi Truck
In the United States most semi trucks have 10 wheels, and the trailer will normally have 8. This can vary if the truck is using super singles, and then will only have 6. The super single tires are becomming more popular than dual wheels.
Trailer is way more bigger than a semi-trailer. Common misconception between a trailer and a semi-trailer. Technically, a trailer has wheels in front and rear and is hitched to a pulling vehicle (car,truck,etc.) A semi- trailer only has wheels in the rear and is hitched to a pulling vehicle (car,truck,etc.)

A semi-trailer truck usually has eighteen wheels. For this reason, many people call semitrailers "18-wheelers". They're also known as "mack trucks", "tractor-trailers", and "big rigs".
The amount of tons a Mac truck can carry will depend on the size of the truck. A six wheel Mac truck with a dump can carry up to 30 tons or more. A Mac truck with 18 wheels and a semi trailer can carry up to 23 tons in the trailer.
The prefix "semi-" means "half", and the standard tractor-trailer articulated vehicle is called a "semi" because of the trailers they pull. A "full" trailer has wheels in the front and back, like a railway car, and connects to the tractor from the front. A "semi-trailer" (or, essentially, "half-trailer") only has wheels in the back, and the front sits over the back wheels of the tractor pulling it.
There are presently no vehicles that have seventeen wheels. Semi trucks come in different sizes, but typically have ten, sixteen, or eighteen wheels. The most common configuration of wheels on large trucks are eighteen wheels, with eight wheels on the cab of the truck, and ten wheel on the trailer.
