A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. [1] A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
When the direct TPMS warning light comes on, either one of the tires is under-inflated, severely over-inflated, or there is a fault with the system. [1] If the light is constant then inflating to the correct placard pressure should turn it off. If this is not the case then this indicates a puncture.
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 ...
Cold inflation pressure is a gauge pressure and not an absolute pressure. This article focuses on cold inflation pressures for passenger vehicles and trucks. The general principles are, of course, applicable to bicycle tires, tractor tires, and any other kind of tire with an internal structure that gives it a defined size and shape (as opposed ...
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 ...
Bicycle floor pump Foot-operated bike pump Frame-mounted bike pump Outdoor public air compressor for bicycles. A bicycle pump is a type of positive-displacement air pump specifically designed for inflating bicycle tires. It has a connection or adapter for use with one or both of the two most common types of valves used on bicycles, Schrader or ...
In the tire factory, the tire and wheel are mounted on a balancing machine test wheel, the assembly is rotated at 100 r/min (about 5–7 m/s (18–25 km/h; 11–16 mph) with recent high sensitivity sensors) or higher, 300 r/min (about 25–27 m/s (90–97 km/h; 56–60 mph) with typical low sensitivity sensors), and forces of unbalance are ...
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.
