A MONSTER TRUCK is a pickup truck modified with a larger suspension and larger tires, usually for recreational uses. Today pickup trucks are still used however, SUV bodies, as well as themed trucks are driven and most of the bodies are now made of fiberglass rather than metal. A competition monster truck should meet guidelines by being 12 feet tall, 12 feet wide, and as of 2015, should be equipped with specifically made 462lb BKT 66-inch off-road tires. Monster trucks used to be side-acts at popular motocross events and mud bogs but today they are usually the main attraction with motocross and mud bogging being the complementary shows.

The first ever created monster trucks were just pickup trucks modified with larger suspension and larger tires. Today, they are built of fiberglass bodies that go onto custom-built tubular chassis. The design of these bodies is primarily to be easily removed and then replaced when damaged. The engine is located just behind the driver and is mostly a supercharged V8 that is propelled by 1.500 HP and goes up to 9.42L(cubic inches). It runs on methyl alcohol and corn-based oil fuel.
There is no more true statement of vehicle’s strength and power!
Axles are mostly taken from big road vehicles such as school busses or heavy-duty military trucks and modified to have a planetary gear reduction at the hub in order to help turn the big tires. All trucks have hydraulic steering on all wheels(four-wheel steering), with the front wheels controlled by the steering wheel and rear ones by the toggle switch.
Tires are manufactured for heavy machines, such as fertilizer spreaders. Because the tires are so huge and contain such a large volume of air in them, they require just 8 to 10 lbs. of air pressure. When landing from a big jump this results in flattening the tires almost completely. In some occasions, tire’s sidewall rolls around the rims during the ground impact and the rim cuts the sidewall. In addition, tires weigh about 880 lbs. and some racing competitors have them modified also by scraping some tread off the tire. They remove about 450 lbs. from a tire, in some cases, in order to reduce weight but also improve truck’s speed overall.
The cabin inside a monster truck is mostly just a series of gauges on board, steering wheel, stick and a centered driver’s seat for the purposes of better view while driving. The seat is bolted to the chassis with layers of high-impact foam strategically positioned throughout. They are made to endure vertical deceleration and allow the driver to make it through each event.
All the components put together right make these amazing vehicles what they are - a modern, unique, frightening monstrosities that can almost “fly”, which makes them even more formidable. There is certainly some kind of strong overwhelming feeling that sticks to viewers at one of the shows when they see 10.000 lbs flying through air dozen feet before them.
