A tire or tyre is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, providing a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, designed to match the vehicle's weight and the bearing on the surface that it rolls over by exerting a pressure that will avoid deforming the surface.
A bicycle brake reduces the speed of a bicycle or prevents the wheels from moving. The two main types are: rim brakes and disc brakes. Drum brakes are less common on bicycles.
Vauxhall Motors Limited is a British car company headquartered in Chalton, Bedfordshire, England. Vauxhall became a subsidiary of Stellantis in January 2021.
The Vauxhall Viva is a small family car that was produced by Vauxhall in a succession of three versions between 1963 and 1979. These were designated the HA, HB and HC series.
The Vauxhall Chevette is a supermini car that was manufactured by Vauxhall in the United Kingdom from 1975 to 1984. It was Vauxhall's version of the "T-Car" small-car family from Vauxhall's parent General Motors (GM), and based primarily on the Opel Kadett C. The family also included the Isuzu Gemini in Japan, the Holden Gemini in Australia, the Chevrolet Chevette in the United States, Canada, Brazil, Colombia, Ecuador and Argentina, and in the U.S. and Canada it was also rebadged as the Pontiac Acadian/Pontiac T1000.
The Opel Calibra is a coupé, engineered and produced by the German automaker Opel between 1989 and 1997. In the United Kingdom, where it remained on sale until 1999, it was marketed under the Vauxhall brand as the Vauxhall Calibra. It was also marketed as the Chevrolet Calibra in South America by Chevrolet, and the Holden Calibra in Australia and New Zealand by Holden.
The Vauxhall Cresta is a British automobile which was produced by Vauxhall from 1954 to 1972. The Cresta was introduced in 1954 as an upmarket version of the Vauxhall Velox, itself a six-cylinder version of the Vauxhall Wyvern. The Cresta models were the E (1954–1957), PA (1957–1962), PB (1962–1965) and PC (1965–1972). The Viscount (1966–1972) was an upmarket Cresta PC.
The Lotus Carlton is a version of the Vauxhall Carlton/Opel Omega A saloon upgraded by Lotus in order to be a high performance sports sedan. Like all Lotus vehicles, it was given a type designation—Type 104 in this case.
The rim is the "outer edge of a wheel, holding the tire". It makes up the outer circular design of the wheel on which the inside edge of the tire is mounted on vehicles such as automobiles. For example, on a bicycle wheel the rim is a large hoop attached to the outer ends of the spokes of the wheel that holds the tire and tube. In cross-section, the rim is deep in the center and shallow at the outer edges, thus forming a "U" shape that supports the bead of the tire casing.
Automotive tires are described by an alphanumeric tire code or tyre code, which is generally molded into the sidewall of the tire. This code specifies the dimensions of the tire, and some of its key limitations, such as load-bearing ability, and maximum speed. Sometimes the inner sidewall contains information not included on the outer sidewall, and vice versa.
A rain tyre or wet tyre is a special tyre used in motorsport in wet weather as opposed to a slick tyre used in dry conditions. It is very similar in many ways to the tyres found on normal road cars.
A flat tire is a deflated 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 puncturing of the tire by a sharp object, such as a nail or pin, letting the air escape. Depending on the size of the puncture, the tire may deflate slowly or rapidly.
A spare tire is an additional tire carried in a motor vehicle as a replacement for one that goes flat, has a blowout, or has another emergency. Spare tire is generally a misnomer, as almost all vehicles actually carry an entire wheel with a tire mounted on it as a spare rather than just a tire, as fitting a tire to a wheel would require a motorist to carry additional, specialized equipment. However, some spare tires are not meant to be driven long distances. Space-savers have a maximum speed of around 50 mph (80 km/h).
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for racing. Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and 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 wind resistance, of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle.
The Scottish Aviation Scamp is a small concept electric city car that was designed between 1964 and 1966 by Scottish Aviation. The name was chosen as a contraction of SCottish and AMP.
A motorcycle tyre is the outer part of motorcycle wheel, attached to the rim, providing traction, resisting wear, absorbing surface irregularities, and allowing the motorcycle to turn via countersteering. The two tyres' contact patches are the motorcycle's connection to the ground, and so are fundamental to the motorcycle's suspension behaviour, and critically affect safety, braking, fuel economy, noise, and rider comfort.
The Vauxhall 30–98 is a car manufactured by Vauxhall at Luton, Bedfordshire from 1913 to 1927. In its day, its best-known configuration was the Vauxhall Velox standard 4-seater with open tourer body. Vauxhall's own description was the 30–98 hp Vauxhall-Velox sporting car. The 30–98 is also known to enthusiasts by Vauxhall's chassis code E.
A railway or railroad is a track where the vehicle travels over two parallel steel bars, called rails. The rails support and guide the wheels of the vehicles, which are traditionally either trains or trams. Modern light rail is a relatively new innovation which combines aspects of those two modes of transport. However fundamental differences in the track and wheel design are important, especially where trams or light railways and trains have to share a section of track, as sometimes happens in congested areas.
The Pirelli Cinturato is a Pirelli-developed car tyre that was the first example of a wrap-around radial tyre structure. It was used to good effect in motorsport, and most modern tyres are based upon the design. The five-times Formula One World Champion Juan Manuel Fangio called the Pirelli Cinturato "Extraordinary" and raced on it many times in the remainder of his career.
