Offroad
Off-roading is the activity of driving or riding in a vehicle on unpaved surfaces such as sand, gravel, riverbeds, mud, snow, rocks, and other natural terrain. Types of off-roading range in intensity, from leisure drives with unmodified vehicles, to competitions with customised vehicles and professional drivers. Off-roaders have been met with criticism for the environmental damage caused by their vehicles. There have also been extensive debates over the role of government in regulating the sport, including a Supreme Court case brought against the Bureau of Land Management in the United States. Off-road vehicle Travelling over difficult terrain requires vehicles capable of off-road driving such as ATVs. These vehicles have features designed specifically for use in off-road conditions such as extended ground clearance, off-road tires and a strengthened drive-train. Some manufacturers offer vehicles specifically designed for off-road use. Recreational off-roading Some exa ...

Axle Articulation
Ramp travel index or RTI, is a way of measuring a vehicle's ability to flex its suspension, a property also known as axle articulation. The RTI rating is used mainly in the off-roading industry to test and describe chassis limits of modified vehicles. The ramps vary between 15 and 30 degrees of angle for the vehicle to ride up. "Ramping" a vehicle involves putting one front tire on the ramp and driving up slowly until one of the other three tires (usually the rear one on the same side as the tire driving the ramp) begins to leave the ground. The measurement is only taken when the other three tires are still on the ground. The distance traveled up the ramp is then measured and is divided by the vehicle's wheelbase and finally multiplied by 1000 to give a final RTI score. Most stock SUVs have RTI values from 400 to 550; vehicles modified for off-road competition have the ability to exceed 1000. Significance of RTI and Axle Articulation A high RTI or good axle articulation is es ...

Toyota Land Cruiser
The (also sometimes spelled as LandCruiser) is a series of four-wheel drive vehicles produced by the Japanese automobile manufacturer Toyota. It is Toyota's longest running series of models. , the sales of the Land Cruiser totalled more than 10 million units worldwide. Production of the first generation of the Land Cruiser began in 1951. The Land Cruiser has been produced in convertible, hardtop, station wagon and cab chassis body styles. The Land Cruiser's reliability and longevity have led to huge popularity, especially in Australia, where it is the best-selling body-on-frame, four-wheel drive vehicle. Toyota also extensively tests the Land Cruiser in the Australian outback considered to be one of the toughest operating environments in both temperature and terrain. In Japan, the Land Cruiser was once exclusive to Toyota Japanese dealerships called ''Toyota Store''. As of 2021, the full-size Land Cruiser was available in many markets. Exceptions include the United States and ...

Unimog U1600
The Unimog (, ) is a range of multi-purpose tractors, trucks and lorries that has been produced by Boehringer from 1948 until 1951, and by Daimler Truck (formerly Daimler-Benz, DaimlerChrysler and Daimler AG) since 1951. In the United States and Canada, the Unimog was sold as the Freightliner Unimog. Unimog production started in 1948 at in Göppingen. Daimler-Benz took over manufacture of the Unimog in 1951, and first produced it in their Gaggenau plant. From 1951, the Unimog was sold under the Mercedes-Benz brand. However, the first Unimog to feature the three-pointed Mercedes-Benz star was only introduced in 1953. Since 2002, the Unimog has been built in the Mercedes-Benz truck plant in Wörth am Rhein in Germany. The Mercedes-Benz Türk A.Ş. plant assembles Unimogs in Aksaray, Turkey. Unimogs were also built in Argentina (first ever country to do so outside Germany) by Mercedes-Benz Argentina S.A. under licence from 1968 until 1983 (with some extra units built until 1991 off ...

Beadlock
A beadlock or bead lock is a mechanical device that secures the bead of a tire to the wheel of a vehicle. Tires and wheels are designed so that when the tire is inflated, the tire pressure pushes the bead of the tire against the inside of the wheel rim so that the tire stays on the wheel and the two rotate together. In situations where tire pressure is insufficient to hold the bead of the tire in place, a beadlock is needed. There are several styles of beadlocks. For 4-wheel drive vehicles, a ring with a number of bolts around the circumference is used to clamp the tire to the wheel. For motorcycles, a rim lock or bead stopper is a curved plate tightened by a single bolt. For both 4-wheel drive vehicles and motorcycles, a different style of beadlock can be used that is similar to an inner tube which is inflated to press the tire against the wheel. Bead lock may also refer to a product used to secure a swimming pool liner into the pool liner track installed on many above ground pool ...

Classic Trials
Classic trials, or colloquially mud plugging, is one of the oldest forms of rallying or off-road motor sports, dating from the beginning of the 20th century. Originally, the challenge was just to complete a long (challenging) road course. All three Motor Cycling Club long distance trials in the UK – the Land's End, the Exeter and the Edinburgh Edinburgh ( ; gd, Dùn Èideann ) is the capital city of Scotland and one of its 32 Council areas of Scotland, council areas. Historically part of the county of Midlothian (interchangeably Edinburghshire before 1921), it is located in Lothian ... – date from that time, and are still held today. As vehicles became more reliable, the events became easier and the concept of ''observed non-stop'' sections was introduced. On these, the car or motorcycle is stopped at the foot of a hill and has to make a non-stop ascent. On a classic trial today, there will typically be around fifteen of such "observed sections", mixed with betw ...

Rockcrawling
Rock crawling is an extreme form of off-road driving using specialized vehicles ranging from stock to highly modified to overcome obstacles. In rock crawling, drivers typically drive highly modified four-wheel-drive vehicles such as trucks, Jeeps, and " buggies" over very harsh terrain. Driving locations include boulders, mountain foothills, rock piles, mountain trails, etc. Rock crawling is about slow-speed, careful and precise driving, and high torque generated through large gear reductions (100:1 or more) in the vehicle's drivetrain. Rock crawlers often drive up, down and across obstacles that appear impassable. Rock crawling competitions range from local events to national series. These consist of long courses with obstacles set up with gates, similar to a slalom ski race. Rock crawling basics The vehicles Vehicles commonly used include Jeep (the Chrysler and the Mitsubishi Varieties), Lada Niva, BAW, Nissan Patrol, Toyota Hilux, Toyota Land Cruiser, Land Rover, Mercedes ...

Tires
A tire (American English) or tyre (British English) is a ring-shaped component that surrounds a Rim (wheel), wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide Traction (engineering), traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, that is designed to match the weight of the vehicle with the bearing strength of the surface that it rolls over by providing a bearing pressure that will not deform the surface excessively. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tire tread, tread and a body. The tread provides Traction (engineering), traction ...

Land Rover Series III Mud Bogging
Land, also known as dry land, ground, or earth, is the solid terrestrial surface of the planet Earth that is not submerged by the ocean or other bodies of water. It makes up 29% of Earth's surface and includes the continents and various islands. Earth's land surface is almost entirely covered by regolith, a layer of rock, soil, and minerals that forms the outer part of the crust. Land plays important roles in Earth's climate system and is involved in the carbon cycle, nitrogen cycle, and water cycle. One-third of land is covered in trees, 15% is used for crops, and 10% is covered in permanent snow and glaciers. Land terrain varies greatly and consists of mountains, deserts, plains, plateaus, glaciers, and other landforms. In physical geology, the land is divided into two major categories: mountain ranges and relatively flat interiors called cratons. Both are formed over millions of years through plate tectonics. A major part of Earth's water cycle, streams shape the lands ...

Spotter (maneuvering)
A spotter is a person used in vehicle maneuvers to assist a driver who may not have a clear view in their direction of travel. They are most commonly used in: * Off-road rock crawling * Reversing truck and trailer combinations, such as semitrailers, b-trains and road trains * Placing oversized freight using a forklift * Lifting loads using a vehicle-mounted crane (loads lifted using a fixed crane are supervised by a banksman In Irish and British civil engineering, a banksman is the person who directs the operation of a crane or larger vehicle from the point near where loads are attached and detached. The term 'dogman' may be used in Australia and New Zealand, while 's ...) * Guiding military vehicles (also called ''ground guiding'') * Dumping materials, such as from a dump truck * Guiding oversized loads. The spotter's advantage is the ability to move around the load or vehicle to determine the best trajectory. A spotter will either use a set of standard hand signals, or will a ...

Road Tax
Road tax, known by various names around the world, is a tax which has to be paid on, or included with, a motorised vehicle to use it on a public road. National implementations Australia All states and territories require an annual vehicle registration fee to be paid in order to use a vehicle on public roads; the cost of which varies from state to state and is dependent on the type of vehicle. The fee is known colloquially as 'rego' (pronounced with a soft g, short for registration). Queensland road tax is based on the number of cylinders or rotors the vehicle's engine has. There is also a small traffic improvement fee. New South Wales road tax is paid based on the vehicle's tare weight. Belgium Passenger cars pay a registration fee based on the engine displacement and power output (degressive towards 2014 (66% in 2012, 33% in 2013, 0% in 2014) and environmental criteria such as CO2 g/km output (increasingly towards 2014). The more CO2 g/km the car produces, the higher the ...
