Properties
There are several properties of motorcycle tyres that influence the performance, handling, and stability of a motorcycle.
- Rolling resistance is the resistance that occurs when a tyre rolls on a flat surface. The rolling resistance coefficients of motorcycle tyres are about 0.02. It tends to increase with forward speed and decrease with inflation pressure.
- Cornering force is the lateral (i.e. parallel to the road surface) force produced by a vehicle tyre during cornering. Cornering force coefficients of motorcycle tyres tends to decrease with increased vertical load, increased inflation pressure, and increased temperature.
- Camber thrust is the force generated perpendicular to the direction of travel of a rolling tyre due to its camber angle and finite contact patch.
- Pneumatic trail is a trail-like effect generated by compliant tyres rolling on a hard surface and subject to side loads, as in a turn. It is the distance that the resultant cornering force of side-slip occurs behind the geometric center of the contact patch.
- Relaxation length describes the delay between when a slip angle is introduced and when the cornering force reaches its steady-state value.

Famous quotes containing the word properties:
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
