These two properties are not linearly proportional to the area of the contact. For example, a 10% change in load or inflation pressure usually does not result in a 10% change in the contact patch area [ 3 ] because the load or pressure on a tire can be altered freely, and the contact patch area is affected by the tire geometry and stiffness.
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 ...
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 ...
Sidewall deflection is not a direct measurement of rolling friction. A high quality tire with a high quality (and supple) casing will allow for more flex per energy loss than a cheap tire with a stiff sidewall. [citation needed] Again, on a bicycle, a quality tire with a supple casing will still roll easier than a cheap tire with a stiff casing ...
Further, at least some motor-paced speed record bicycles have used Schrader valves. (The actual speed of Schrader opening depends on many factors; 150 kph is only a very rough guide. The important observation is a Presta valve's nut is not an advantage in actual use, because ordinary bicycles do not go fast enough for it to matter.)
Nissan is urging the owners of about 84,000 older vehicles to stop driving them because their Takata air bag inflators have an increased risk of exploding in a crash and hurling dangerous metal ...
A beadlock or bead lock is a mechanical device that secures the bead of a tire to the wheel of a vehicle. Tires and wheels are designed so that when the tire is inflated, the tire pressure pushes the bead of the tire against the inside of the wheel rim so that the tire stays on the wheel and the two rotate together.
