Part 99 - The Role of a Motorcycle Tyre... (",)

The Role of a Motorcycle Tyre

Technical Details

Tread pattern: The grooves in the tyre enable it to evacuate water from the contact patch when the road is wet. The more grooves there are, the better the tyre will perform in the rain. A worn tread pattern with few grooves indicates that the tyre should be replaced.



Rubber mix: The rubber’s chemical makeup determines durability and grip . A softer rubber compound promotes cornering grip and traction. A harder rubber compound wears more slowly. Silica -reinforced compounds excel in the wet.



Profile: The tyre’s profile (cross-section) can have a strong influence on the dynamic behavior of a motorcycle. Sport tyres promote quick steering and extreme lean angles. Street tyres emphasize stability and low-speed maneuverability.



Tread area: The only point of contact between the motorcycle and the ground. The rubber mix in this area is often different from that on the tyre’s sidewalls. In addition to absorbing bumps to ensure a comfortable ride, the center of the tread is the part of the tyre that must be the most resistant to wear.



Carcass: Supports the load of the motorcycle, ensures stability and contributes to comfort . The carcass must allow some deformation to absorb road shock. Radial carcasses are more flexible than traditional bias-ply construction and thus offer superior damping.



Radial construction: A structure composed of carcass plies perpendicular to the direction of rotation (90 degrees), with additional cross-plies on top and/or a crown ply at 0 degrees. A radial is made up of fewer components than a bias-ply tyre. Thus it is lighter, and offers improved handling. Also with fewer components, there is less internal friction and reduced operating temperature at high speeds. With a radial tyre, designers can use more aggressive tread compounds that combine durability and grip.
