A monster truck is a giant truck that rides on tires taller than a grown-up. It is built to drive right over cars and crush them flat. A monster truck can also race up dirt ramps and jump high into the air. It looks like a pickup truck, but much, much bigger.
Why monster trucks are tricky to understand
A monster truck looks like a normal pickup truck that grew huge. But it is not really a regular truck at all. Builders make a monster truck from special strong parts so it can jump and land hard.
The tires are the first big surprise. Each tire stands about 66 inches (1.7 m) tall. That is taller than most adults. You could not even reach the top of one tire.
The next surprise is how heavy it is. A monster truck weighs about 10,000 pounds (4,500 kg). That is about the same as a few cars stacked together. All that weight helps the truck squash cars when it drives over them.
Key facts about monster trucks
The tires are taller than a person. Each tire is about 66 inches (1.7 m) tall. That is taller than most grown-ups.
A monster truck is very heavy. It weighs about 10,000 pounds (4,500 kg), about as much as a few cars.
The first monster truck was BIGFOOT. A man named Bob Chandler built it from a Ford pickup truck in the 1970s.
Grave Digger is one of the most famous. It is painted black and green and was built by a driver named Dennis Anderson.
Monster trucks crush cars. The huge tires and heavy weight squash old cars flat.
Monster trucks jump far. The longest jump on record went more than 200 feet (61 m) through the air.
The body is light. The colorful outer shell is made of fiberglass, a light material, so the truck can jump higher.
The engine is loud. A monster truck has a big, powerful engine that makes a deep, growling roar.
Shows happen in big stadiums. Workers bring in tons of dirt to build ramps and hills for the trucks.
Common myths about monster trucks
Myth: A monster truck is just a normal pickup with big tires. A monster truck is built from special strong parts, not from a regular truck with bigger wheels. It has a strong frame made to jump and land hard.
Myth: The body is made of heavy steel. The outer body is made of light fiberglass, not steel. A light body helps the truck jump higher and turn faster.
Myth: Monster trucks are too heavy to jump. Monster trucks are heavy, but they jump very far. The longest jump on record went more than 200 feet (61 m).
Myth: Any truck can do a backflip. A backflip is one of the hardest tricks in the sport. It takes a special truck and a very skilled driver to flip all the way over and land safely.
Myth: Monster trucks run on regular gas like a family car. Monster trucks burn a special fuel called methanol. It is not the same as the gas people put in a normal car.
Frequently asked questions about monster trucks
How big are monster truck tires?
Monster truck tires are about 66 inches (1.7 m) tall. That makes each tire taller than most grown-ups. The tires are also very wide, about 43 inches (110 cm) across, so the heavy truck can roll over cars and dirt.
How much does a monster truck weigh?
A monster truck weighs about 10,000 pounds (4,500 kg). That is about the same as a few regular cars put together. All that weight helps the truck crush cars and land safely after a jump.
What was the first monster truck?
The first monster truck was called BIGFOOT. A man named Bob Chandler built it from his Ford pickup truck in the 1970s. He kept adding bigger tires and stronger parts until the truck became a giant.
How high can a monster truck jump?
Monster trucks jump high off dirt ramps. The longest jump on record went more than 200 feet (61 m) through the air. That is longer than two-thirds of a football field.
What is a monster truck made of?
The bright outer body is made of fiberglass, which is light and strong. Under that body is a frame made of strong metal tubes. The light body and strong frame let the truck jump and land without breaking.

A monster truck is a purpose-built truck that rides on tires about 66 inches (1.7 m) tall and is made to crush cars and jump off dirt ramps. It looks like a giant pickup, but builders construct it from a strong metal frame and racing parts rather than from a normal truck. A modern competition monster truck weighs about 10,000 pounds (4,500 kg) and is powered by a loud, high-powered engine. These trucks star in arena and stadium shows watched by huge crowds.
Why monster trucks surprise people
The biggest surprise about a monster truck is that it is not a stock pickup with oversized wheels. It only looks that way. Underneath the bright body is a frame built from welded metal tubes, plus suspension and tires designed for hard landings.
The tires alone are taller than most adults. Each one stands about 66 inches (1.7 m) tall and 43 inches (110 cm) wide. With its wheel, a single tire weighs around 645 pounds (293 kg). The four tires together make up a large part of the truck’s weight.
Another surprise is the engine. A monster truck does not run on regular gas. It burns methanol, a racing fuel that helps the engine make a lot of power. That power lets a heavy truck launch off a ramp and fly through the air.
Key facts about monster trucks
The tires are about 66 inches (1.7 m) tall. Each one is also about 43 inches (110 cm) wide, taller and wider than most grown-ups.
A monster truck weighs about 10,000 pounds (4,500 kg). That is roughly the weight of several regular cars.
The first monster truck was BIGFOOT. Bob Chandler built it from a Ford F-250 pickup in the 1970s, and it is widely called the world’s first monster truck.
Grave Digger is one of the most famous. Dennis Anderson created it in the early 1980s and painted it black and green.
Monster trucks burn methanol fuel. This racing fuel is different from the gas in a family car and helps the engine make more power.
The body is fiberglass. The colorful outer shell is light, so the truck can jump higher and turn faster.
The longest jump went more than 200 feet (61 m). Driver Joe Sylvester set the record of 237 feet 7 inches (about 72 m) in 2013.
Monster Jam is the biggest tour. It is run by a company called Feld Entertainment and puts on hundreds of shows each year.
Skilled drivers can do a backflip. Cam McQueen landed the first one in a scored competition in 2010.
Common myths about monster trucks
Myth: A monster truck is just a pickup with bigger tires. A monster truck is built around a strong tube frame with racing suspension. A regular pickup frame could not survive the landings. The pickup-like body is only a shell on top.
Myth: The body is made of steel. The outer body is made of lightweight fiberglass, not steel. Steel would add too much weight and lower the truck’s jumps. Keeping the body light helps the truck fly higher.
Myth: Monster trucks use the same gas as a family car. Monster trucks run on methanol, a special racing fuel. Methanol lets the engine make far more power than regular gas would.
Myth: Any truck can do a backflip. A backflip is one of the hardest tricks in the sport. It takes a purpose-built truck and a very skilled driver to flip all the way over and land back on the tires.
Myth: Grave Digger was the first monster truck. BIGFOOT came first, in the 1970s. Dennis Anderson built the first Grave Digger later, in the early 1980s.

A monster truck is a purpose-built competition vehicle that combines a pickup-style fiberglass body with oversized off-road tires, a tube-frame chassis, and a high-output engine, designed to crush cars and perform jumps and stunts. Modern competition trucks ride on tires about 66 inches (1.7 m) tall, weigh at least 10,000 pounds (4,500 kg), and use a supercharged, methanol-burning V8 producing roughly 1,500 horsepower. The form began in the late 1970s with BIGFOOT and grew into a stadium and arena sport now led by the touring series Monster Jam. The trucks are judged in two formats: head-to-head racing and a points-scored freestyle.
Why the engineering is more than big tires
The popular image of a monster truck is a stock pickup fitted with huge wheels. The reality is closer to a custom off-road race car wearing a pickup costume. The visible body panels are lightweight fiberglass and serve mainly to identify the truck and shape airflow. They carry no structural load.
The strength comes from a tube-frame chassis, a skeleton of welded steel tubing that ties the engine, suspension, and driver’s cage together. This chassis absorbs the force of repeated hard landings. A stock pickup frame, built for road use, would bend or break under the same impacts.
Suspension is the other half of the story. Each wheel rides on a four-link suspension with long travel, giving the wheel up to about four feet (1.2 m) of vertical movement. Large shocks charged with nitrogen gas help control that movement. When a 10,000-pound truck lands from a jump, the long-travel suspension spreads the impact over a greater distance and protects both the chassis and the driver.
The tires and the engine
The tires define the look of the sport. A competition tire stands about 66 inches (1.7 m) tall and 43 inches (110 cm) wide, mounted on a 25-inch (64 cm) wheel. With the wheel attached, each tire weighs around 645 pounds (293 kg) and is inflated to a low pressure, roughly 23 psi. The low pressure lets the tire flex and absorb shock on landing rather than bouncing the truck.
The engine sits behind the driver in most modern designs. It is a supercharged V8 burning methanol, a fuel that supports high power output. Major series cap engine displacement at up to about 575 cubic inches (9.4 liters), and within that limit a competition engine produces roughly 1,500 horsepower. That figure is several times the output of a typical family car and is what allows a heavy truck to accelerate hard and launch off ramps.
Most trucks also use hydraulic steering at both the front and rear axles. Steering the rear wheels separately lets a long, heavy truck turn within the tight space of an arena floor. The combination of rear steer, long-travel suspension, and high power is what makes the trucks agile despite their weight.
Safety: the Remote Ignition Interrupter
A monster truck that loses control while still running is dangerous, so the sport relies on a remote shut-off. Each competition truck carries a Remote Ignition Interrupter, usually shortened to RII. The device lets a safety official, called an event steward, cut the engine by radio if a truck rolls or heads toward the crowd.
The RII became standard in the late 1980s. After several incidents in which trucks rolled and kept running, builders worked with the sport’s racing association to require a remote kill system. A handheld transmitter sends a signal that shuts off the ignition, stopping the engine even when the driver cannot. Trucks also carry shut-off switches inside the cab and on the body so that the driver and the recovery crew can stop the engine by hand.
A short history
The sport traces to Bob Chandler, a four-wheel-drive enthusiast in St. Louis. In the mid-1970s he began modifying his Ford F-250 pickup with larger tires and stronger axles, building the truck he named BIGFOOT. By the end of the decade it had grown into what is now seen as the world’s first monster truck.
In 1981, Chandler drove BIGFOOT over a pair of cars in a field, footage that was filmed at first as a kind of test. Crushing cars soon became the act the sport is known for. BIGFOOT 2 introduced the now-standard 66-inch (1.7 m) tires in late 1982 at the Pontiac Silverdome.
Other famous trucks followed. Dennis Anderson built the first Grave Digger in the early 1980s as a mud-bog racer near his home in North Carolina, later rebuilding it into a full monster truck. The name came from his boast that he would dig his rivals a grave with the old truck. Painted black and green, Grave Digger became one of the most recognized trucks in the sport.
The trucks grew into a stadium attraction, and the touring series Monster Jam, run by Feld Entertainment, became the largest in the world. Monster Jam puts on hundreds of live events each year and crowns champions at a season-ending World Finals.
Records and formats
Monster trucks hold several Guinness World Records. The longest ramp jump is 237 feet 7 inches (72.42 m), set by Joe Sylvester driving Bad Habit in 2013, longer than two-thirds of an American football field. The fastest recorded speed is 101.84 miles per hour (163.89 km/h), also set by Joe Sylvester, in 2022. Skilled drivers have also landed backflips, a trick first completed in a scored competition by Cam McQueen in 2010.
A Monster Jam event is built around two main competitions. In racing, trucks go head-to-head over a course, and the first truck to legally finish advances. In freestyle, each driver has a set time to perform jumps and stunts across the floor, and a panel of judges scores the run. Events often add skills contests such as the two-wheel challenge and donuts, both judged.

Common myths about monster trucks
Myth: A monster truck is a stock pickup with big tires. The body is a fiberglass shell; the strength comes from a purpose-built tube-frame chassis with racing suspension. A factory pickup frame would not survive the landings.
Myth: The body is steel. The body is lightweight fiberglass. Steel would add weight and reduce the truck’s ability to jump.
Myth: Monster trucks run on ordinary gas. Competition trucks burn methanol, a racing fuel that supports far higher power than pump gas.
Myth: Any truck can do a backflip. A backflip requires a purpose-built truck and an expert driver. It was first landed in a scored competition only in 2010.
Myth: There is no way to stop a runaway truck except the driver. Each truck carries an RII that lets officials cut the engine remotely, exactly for moments when the driver cannot stop the truck.

A monster truck is a purpose-built off-road competition vehicle in which a lightweight pickup-style body is mounted over a welded tube-frame chassis, oversized off-road tires, long-travel suspension, and a high-output engine, configured to crush cars and perform jumps, wheelies, and freestyle stunts. The defining specifications of a modern competition truck are tires about 66 inches (1.7 m) tall, a minimum weight of 10,000 pounds (4,500 kg), and a supercharged, methanol-burning V8 producing roughly 1,500 horsepower. The form originated in the late 1970s with Bob Chandler’s BIGFOOT and matured into a stadium and arena sport now led by Monster Jam, run by Feld Entertainment. The two competition formats are head-to-head racing and judged freestyle.
Why a monster truck is a custom racer, not a modified pickup
The pickup body is a costume. The visible panels are lightweight fiberglass, chosen to keep mass low and to identify the truck; they bear no structural load. Every load path runs through a separate chassis built specifically for the sport.
That chassis is a space frame of welded steel tubing, most often drawn-over-mandrel mild steel or 4130 chromoly tubing for the highest-stress members. The frame integrates the engine mounts, the suspension pickup points, and a driver’s cage. It is engineered to take the repeated shock of landing a vehicle that masses several tons from heights of a few stories. A production pickup frame, optimized for road durability and crash structure rather than for jump impacts, would deform under the same loads.
The same logic applies to the driveline. Power passes through a transmission and transfer case to axles fitted with planetary final-drive reductions at the hubs. Placing a large reduction at the planetaries lowers the torque carried by the ring and pinion, driveshafts, and transfer case, which protects those parts from the enormous torque of the engine. The result is a vehicle that only resembles a pickup in silhouette.
Suspension and the physics of landing
Suspension is where a monster truck earns its survivability. Each corner uses a four-link arrangement, with four locating bars tying an axle to the frame so the axle can move vertically through a long stroke while staying aligned. The wheel travel is very long by road-vehicle standards, with builds offering roughly 30 inches of movement.
Damping comes from clusters of shocks charged with nitrogen gas rather than from steel coil springs alone. Nitrogen charging keeps the damper consistent under repeated, high-energy compression and resists the fade that would affect a fluid-only damper as it heats. The long stroke matters for a simple reason rooted in physics: the force a landing imposes scales with how quickly the truck’s downward motion is arrested. Spreading that deceleration over a greater distance reduces the peak force on the chassis and on the driver. A truck with little travel would transmit a violent shock; a truck with two and a half feet of travel turns the same landing into a long, controlled compression.
The engine: supercharged methanol V8
The engine is the loudest and most demanding system on the truck. A common configuration is a big-block V8 of roughly 540 cubic inches, with major series capping displacement at up to about 575 cubic inches (9.4 liters). A belt-driven supercharger, often called a blower, force-feeds an air-and-fuel charge into the engine and is the main reason a naturally modest displacement reaches roughly 1,500 horsepower along with very high torque.
The fuel is methanol, and the choice is deliberate. Methanol burns cooler than gasoline and carries a large heat of vaporization, so as it changes from liquid to vapor in the intake it draws heat out of the incoming charge. That charge cooling lets a heavily boosted engine survive extreme internal temperatures and tolerate higher cylinder pressures without detonation. The trade is consumption: a competition engine drinks methanol at a high rate, on the order of several gallons per minute during a run, fed from a dedicated safety fuel cell.
Most trucks steer hydraulically at both the front and rear axles. Independent rear steer lets a long, heavy vehicle rotate within the confined geometry of an arena floor, supporting tight racing lines and the rapid rotation of a donut.
Safety engineering: the Remote Ignition Interrupter
A powered, out-of-control truck is the central hazard of the sport, and the countermeasure is a remote engine kill. Every competition truck carries a Remote Ignition Interrupter, usually shortened to RII, which lets a safety official, called an event steward, cut the ignition by radio when a truck rolls or tracks toward the crowd.
The system arose from hard experience. After a sequence of incidents in the late 1980s in which trucks rolled and kept running, builders and the sport’s racing association adopted a mandatory remote shut-off. A handheld transmitter sends the kill signal; redundant cut-off switches are also fitted inside the cab and on the body so the driver and the recovery crew can stop the engine manually. The RII is the reason an official outside the truck, rather than the driver alone, can end an engine event in the moment it becomes dangerous.
From BIGFOOT to a global tour
The sport begins with Bob Chandler in St. Louis. In the mid-1970s he modified his Ford F-250 with progressively larger tires and stronger axles, creating the truck he named BIGFOOT. By the end of the decade it had become what is now recognized as the world’s first monster truck. In 1981 Chandler drove BIGFOOT over a pair of cars in a field, footage shot at first as a test, and car crushing soon became the act the sport is known for. BIGFOOT 2 introduced the now-standard 66-inch (1.7 m) tires in late 1982 at the Pontiac Silverdome.
Display trucks pushed the scale further. BIGFOOT 5, built in 1986, rides on 10-foot tires sourced from a US Army overland train used in Alaska in the 1950s and stands about 15 feet 6 inches (4.7 m) tall, recognized as the largest monster truck. It is a fairgrounds and exhibition piece rather than a competition truck.
Other names defined the era of arena competition. Dennis Anderson built the first Grave Digger in the early 1980s as a mud-bog racer in North Carolina, later rebuilding it into a full monster truck; the name came from his boast that he would dig his rivals a grave with the old truck. Painted black and green, Grave Digger became one of the most recognized vehicles in motorsport. The sport consolidated into Monster Jam, the largest touring series, run by Feld Entertainment, which stages hundreds of live events each year and crowns champions at a season-ending World Finals.
Records and competition formats
Monster trucks hold several Guinness World Records. The longest ramp jump is 237 feet 7 inches (72.42 m), set by Joe Sylvester driving Bad Habit in 2013, a distance longer than two-thirds of an American football field. The fastest recorded speed is 101.84 miles per hour (163.89 km/h), also by Joe Sylvester, in 2022. The first monster truck backflip landed in a scored competition is credited to Cam McQueen in 2010.
A Monster Jam event is structured around two judged or timed disciplines. Racing is head-to-head over a course, advancing the first truck to legally finish. Freestyle gives each driver a fixed window to perform jumps and stunts across the floor, scored by a panel on factors such as difficulty, variety, and use of the course. Skills contests, including a two-wheel challenge and donuts, are also judged. The split between objective racing and subjective freestyle is what lets a truck win on outright speed in one segment and on creative aggression in another.

Common misconceptions at expert level
Misconception: A monster truck is a heavily modified production pickup. The pickup body is non-structural fiberglass. The vehicle is a bespoke space-frame off-road racer with custom axles, suspension, and engine; the production resemblance is cosmetic.
Misconception: The body provides crash protection. Occupant protection comes from the steel tube cage and restraint system, not the fiberglass shell. The shell is sacrificial and aerodynamic.
Misconception: Methanol is used only because it is cheap. Cost is secondary. The dominant reasons are charge cooling from its high heat of vaporization and its resistance to detonation under heavy boost, which let the engine survive extreme cylinder conditions.
Misconception: Big tires alone explain the jumps. Survivable jumping depends on long-travel four-link suspension and nitrogen dampers that spread landing forces over a long stroke. Tire size sets ground clearance and footprint, but the suspension manages the impact.
Misconception: Only the driver can stop a runaway truck. The RII lets an external official kill the engine by radio. The system exists precisely for the cases in which the driver cannot stop the truck.
Frequently asked questions about monster trucks
What is a monster truck chassis made of?
It is a welded tubular steel space frame, commonly drawn-over-mandrel mild steel with 4130 chromoly tubing for the most highly stressed members. The fiberglass body bolts over this frame and carries no structural load. The chassis integrates the engine mounts, suspension pickups, and the driver’s cage.
Why do monster trucks use methanol instead of gasoline?
Methanol burns cooler than gasoline and absorbs heat as it vaporizes in the intake, cooling the incoming charge. That charge cooling, along with methanol’s resistance to detonation, lets a heavily supercharged engine run high cylinder pressures and survive extreme temperatures. The cost is high fuel consumption, on the order of several gallons per minute.
How much suspension travel does a monster truck have?
Competition trucks use long-travel four-link suspension with nitrogen-charged shocks, with builds offering roughly 30 inches of wheel movement. The long stroke spreads the deceleration of a landing over a greater distance, lowering the peak force on the chassis and driver.
What was the first monster truck, and what is the largest?
BIGFOOT, built by Bob Chandler from a Ford F-250 in the 1970s, is credited as the world’s first monster truck. The largest is BIGFOOT 5, built in 1986, standing about 15 feet 6 inches (4.7 m) tall on 10-foot tires from a 1950s US Army overland train.
How do officials stop a monster truck in an emergency?
Each truck carries a Remote Ignition Interrupter (RII). A safety official, the event steward, holds a transmitter that cuts the engine by radio if a truck rolls or heads toward the crowd. The mandatory remote kill was adopted in the late 1980s after a series of crashes, and redundant manual switches are fitted in the cab and on the body.
