A clincher bicycle tire mounted on a wheel A cross section of a clincher tire with a puncture-preventing layer (in blue) between the casing and the tread An inner tube rolled up for storage or to be carried as a spare. A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle.
The combination of a tubular tyre and its tubular rim is lighter than that of a clincher tyre and clincher rim, and will therefore always result in less rotating mass or a stronger construction. [5] Tubulars can also be used over a wider range of tyre pressures from 1.7 to 14 bar (25 to 200 psi), compared to the typical 6-9 bar on a clincher tyre.
Most bicycle rims are "clincher" rims for use with clincher tires. These tires have a wire or aramid ( Kevlar or Twaron ) fiber bead that interlocks with flanges in the rim. A separate airtight inner tube enclosed by the rim supports the tire carcass and maintains the bead lock.
Tire bead is the term for the edge of a tire that sits on the rim. Wheels for automobiles, bicycles, etc. are made with a small slot or groove into which the tire bead sits. When the tire is properly inflated, the air pressure within the tire keeps the bead in this groove. Reducing tire air pressure is a frequent practice among off-road vehicle ...
Valve stem: Pneumatic tires receive their air through a valve stem—a tube made of metal or rubber, with a check valve, typically a Schrader valve on automobiles and most bicycle tires, or a Presta valve on high-performance bicycles. They mount directly to the rim, in the case of tubeless tires, or are an integral part of the inner tube.
In the past, car tires used inner tubes, but most cars now use tubeless tires that hold air without an inner tube. Tubeless tires offer advantages, as they can operate at both low and high pressures without the risk of pinching or bursting, unlike tube tires. [2] Large inner tubes are used for various recreational activities, such as flotation ...
A tire-pressure gauge, or tyre-pressure gauge, is a pressure gauge used to measure the pressure of tires on a vehicle. Proper tire pressure is crucial for vehicle safety, fuel efficiency, and tire longevity. Tire gauges come in various types, including analog, digital, and dial gauges, each offering different features and accuracy levels.
The Presta valve (also French valve (FV) or Sclaverand valve) is a type of tire valve commonly found on high pressure bicycle inner tubes and is commonly used on tubeless setups. It consists of an outer valve stem and an inner valve body. A lock nut to secure the stem at the wheel rim and a valve cap may also be present.
