Average weight of semi tractor and 48ft trailer?

Semi-tractors (also known as semis or big rigs) are large commercial vehicles that are used to transport goods. They are typically powered by diesel engines and can have multiple trailers attached to them. The average weight of a semi-tractor can range from 15,000 to 20,000 pounds (6,800 to 9,000 kilograms).

48ft trailers are a type of semi-trailer that is commonly used to transport goods. They are typically made of aluminum or steel and can weigh up to 10,000 pounds (4,500 kilograms) when empty. The average weight of a 48ft trailer loaded with goods can range from 25,000 to 40,000 pounds (11,000 to 18,000 kilograms).

Therefore, the average weight of a semi tractor and 48ft trailer can range from 40,000 to 60,000 pounds (18,000 to 27,000 kilograms).
