Monstrous trucks are customized trucks with heavy-duty suspension, four-wheel steering, and oversized tires used for competitive and entertainment purposes. In the beginning, they were produced by altering stock pickup trucks and sport utility vehicles (SUVs). Still, today they are purpose-built cars with tube-frame chassis and fibreglass body panels rather than metal. A competition monster truck is generally up to 3.7 meters tall and equipped with off-road tires up to 1.7 meters in diameter. Monster trucks are pretty famous for some reason. A super-jacked truck with wheels more prominent than your house can cause blood to gush and the crackles and howls to reach dangerous levels.
