Airless Tire
Airless tires, non-pneumatic tires (NPT), or flat-free tires are tires that are not supported by air pressure. They can be used on small vehicles such as ride-on lawn mowers and golf cart, motorized golf carts. They also are used on heavy equipment required to operate on sites where risk of tire punctures is high. Tires composed of closed-cell polyurethane foam are also made for bicycles and wheelchairs. Advantages & disadvantages The main advantages of airless tires is that they do not go flat and need to be replaced less frequently. Heavy equipment outfitted with airless tires will be able to carry more weight and engage in more rugged activities. Airless tires generally have higher rolling resistance and provide somewhat less suspension than similarly shaped and sized Tire, pneumatic tires. Other problems for airless heavy equipment tires include dissipating the heat buildup that occurs when they are driven. Airless tires are often filled with compressed polymers (plastic) ra ...

5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. Humans, and many other animals, have 5 digits on their limbs. Mathematics 5 is a Fermat prime, a Mersenne prime exponent, as well as a Fibonacci number. 5 is the first congruent number, as well as the length of the hypotenuse of the smallest integer-sided right triangle, making part of the smallest Pythagorean triple ( 3, 4, 5). 5 is the first safe prime and the first good prime. 11 forms the first pair of sexy primes with 5. 5 is the second Fermat prime, of a total of five known Fermat primes. 5 is also the first of three known Wilson primes (5, 13, 563).

Bicycle Tire
A bicycle tire is a tire that fits on the Bicycle wheel, wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for Wheelchair racing, racing. Bicycle tires provide an important source of Bicycle suspension, suspension, generate the lateral forces necessary for Bicycle and motorcycle dynamics#Balance, balancing and Bicycle and motorcycle dynamics#Turning, turning, and generate the longitudinal forces necessary for Vehicle propulsion, propulsion and Bicycle brake systems, braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically the second largest source, after Drag (physics), wind resistance (air drag), of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle. Bicycle tires are also used on unicycles, tricyc ...

Run-flat Tire
A run-flat tire is a pneumatic vehicle tire designed to resist the effects of deflation when punctured, allowing the vehicle to continue to be driven at reduced speeds for limited distances. First developed by tire manufacturer Michelin in the 1930s, run-flat tires were introduced to the public market in the 1980s. They have increased in popularity over time. Technologies There are three basic technologies currently available, described below. Self-supporting The origins of the commercial ''self-supporting'' run-flat tire started in 1935 with a tire that had a fabric inner tire. The tire was advertised as a protection against blowouts, a common and dangerous occurrence in the 1930s. In 1934, Michelin introduced a tire that was based on technology developed for local commuter trains and trolleys. It had a safety rim inside the tire which if punctured would run on a special foam lining. The tire was sold for military use and for specialized vehicles like bank armoured cars. It was ...

Humvee
The High Mobility Multipurpose Wheeled Vehicle (HMMWV; colloquial: Humvee) is a family of Military light utility vehicle, light, four-wheel drive Military vehicle#Military trucks, military trucks and utility vehicles produced by AM General. It has largely supplanted the roles previously performed by the Willys MB, original jeep, and others such as the Vietnam War-era M151 ¼-ton 4×4 utility truck, M151 Jeep, the M561 "Gama Goat", their M718A1 and M792 ambulance versions, the Commercial Utility Cargo Vehicle, and other light trucks. Primarily used by the United States military, it is also used by numerous other countries and organizations and even in civilian adaptations. The Humvee saw widespread use in the Gulf War of 1991, where it navigated the desert terrain; this usage helped to inspire civilian Hummer versions. The vehicle's original unarmored design was later seen to be inadequate and was found to be particularly vulnerable to improvised explosive devices in the Iraq Wa ...

Tweel
The Tweel (a portmanteau of ''tire'' and ''wheel'') is an airless tire design developed by the French tire company Michelin. Its significant advantage over pneumatic tires is that the Tweel does not use a bladder full of compressed air, and therefore cannot burst, leak pressure, or become flat. Instead, the Tweel's hub is connected to the rim via flexible polyurethane spokes which fulfil the shock-absorbing role provided by the compressed air in a traditional tire. Design The Tweel consists of a band of conventional tire rubber with molded tread, a shear beam just below the tread that creates a compliant contact patch, a series of energy-absorbing polyurethane spokes, and an integral inner hub structure. Both the shear beam and the polyurethane spokes can be designed to provide a calibrated directional stiffness in order to control both how the Tweel handles and how it handles loads. The inner hub structure may be either rigid or compliant, depending on the application requi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bicycle-sharing System
A bicycle-sharing system, bike share program, public bicycle scheme, or public bike share (PBS) scheme, is a shared transport service where bicycles are available for shared use by individuals at low cost. The programmes themselves include both docking and dockless systems, where docking systems allow users to rent a bike from a dock, i.e., a technology-enabled bicycle rack and return at another node or dock within the system – and dockless systems, which offer a node-free system relying on smart technology. In either format, systems may incorporate smartphone web mapping to locate available bikes and docks. In July 2020, Google Maps began including bike share systems in its route recommendations. With its antecedents in grassroots mid-1960s efforts; by 2022, approximately 3,000 cities worldwide offer bike-sharing systems, e.g., Dubai, New York City, New York, Paris, Ecobici (Mexico City), Mexico City, Montreal and Barcelona.

Flat Tire
A flat tire (British English: flat tyre) is a deflated Tire, pneumatic tire, which can cause the rim of the wheel to ride on the tire tread or the ground potentially resulting in loss of control of the vehicle or irreparable damage to the tire. The most common cause of a flat tire is the puncturing of the tire by a sharp object, such as a nail (fastener), nail or pin, letting the air escape. Depending on the size of the blowout, the tire may deflate slowly or rapidly. Besides puncturing of the tire a flat can be caused by: failure of or damage to the valve stem (tire), valve stem; a nail in the tire; rubbing of the tire against the road; ripping of the tire; separation of tire and rim by collision with another object; excessive wear of the tire Tire tread, tread allowing explosive tire failure or road debris tearing through the tire. Some tyres, particularly those with a slow leak, can be repaired and re-inflated; others, especially those with worn tread, must be replaced. Drivi ...
