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 ...
Motor vehicles are normally equipped for changing a tire. These tools include a jack, a tire iron or lug wrench, and a spare tire. Air pumps run by hand-lever, pressure cans, or electricity can be used to re-inflate slow-leaking tires. One common way to temporarily repair and re-inflate a punctured tire at the roadside is to use a canned tire ...
If the tire is not checked, it has the potential to cause vibration in the suspension of the vehicle on which it is mounted. In tire retail shops, tire/wheel assemblies are checked on a spin-balancer, which determines the amount and angle of unbalance. Balance weights are then fitted to the outer and inner flanges of the wheel. [2]
The recommended inflation pressure is found in the owner's manual and on the vehicle's tire placard. [ 3 ] [ 4 ] Because of slow air leaks, changes in the weather and ambient temperature or other conditions, tire pressure will occasionally have to be corrected via the valve stem with compressed air which is often available at service stations.
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 ...
Moreover, running a tire even briefly on inadequate pressure breaks down the casing and prevents the ability to retread. Not all sudden tire failures are caused by under-inflation. Structural damages caused, for example, by hitting sharp curbs or potholes, can also lead to sudden tire failures, even a certain time after the damaging incident.
Inflating a bicycle tire equipped with a Presta or Dunlop valve at an automobile filling station requires an adaptor, while a Schrader-valved tube does not. Inflating at home or on the road requires either 6mm air chuck for Presta and Dunlop valves, or an 8mm chuck for Schrader valves. An important advantage of Schrader valves relative to ...
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.
