Clincher tires can be mounted on straight-side or crochet-type rims. Crochet-type rims are not the same as hooked-bead rims. Such tires are designated with their nominal section width and their nominal rim diameter, separated by a hyphen (-). Both are measured in millimeters. A typical example of a tire marking according to ISO 5775-1 is:
Some such pumps are designed to cut off before a suitable pressure (much higher for a bicycle than a car tire), and will much under inflate the tire. Others may not cut off, but deliver a high rate of flow to fill the larger car tire, with a risk of over inflating and bursting a bicycle tire unless it is stopped with split-second timing.
The Dunlop valve, (also called a Woods valve, an English valve or a Blitz valve [1]) is a type of pneumatic valve stem in use—mostly on inner tubes of bicycles—in many countries, including Japan, [2] Korea, India, Pakistan, Sri Lanka, most European countries, and a number of developing countries.
Air pressure in an automobile tire relative to atmosphere (gauge pressure) [citation needed] +210 to +900 kPa +30 to +130 psi Air pressure in a bicycle tire relative to atmosphere (gauge pressure) [57] 300 kPa 50 psi Water pressure of a garden hose [58] 300 to 700 kPa 50–100 psi Typical water pressure of a municipal water supply in the US [59]
For low inflation pressures, this distinction is more important, as the ideal gas law applies to absolute pressure, including atmospheric pressure. For example, if a fat-bike tire is inflated to 0.5 bar (50 kPa; 7.3 psi) gauge pressure at room temperature 20 °C (68 °F) and then the temperature is decreased to −10 °C (14 °F) (a 9% decrease ...
Colorized tire footprint pressure distribution. The contact patch is the portion of a vehicle's tire that is in actual contact with the road surface.It is commonly used in the discussion of pneumatic (i.e. pressurized) tires, where the term is used strictly to describe the portion of the tire's tread that touches the road surface.
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.
