Motorcycle tyre and pair of motorcycle tyres

A motorcycle tyre comprising a tread band comprising a central portion and two shoulder portions arranged at axially opposite sides of the central portion, wherein:

• the central portion comprises a first plurality of grooves extended according to a substantially longitudinal direction and alternatively arranged at opposite sides of an equatorial plane of said tyre, wherein each groove of said first plurality of grooves has a substantially curvilinear course thereby forming a concavity;
• the central portion comprises a sub-portion substantially free of grooves placed astride an equatorial plane of said tyre;
• each of said shoulder portions comprises a second plurality of grooves arranged obliquely relative to the equatorial plane of said tyre;
• and
• said second plurality of grooves comprises a set of groove pairs, wherein at least one extension of each groove pair of said second plurality of grooves intersects a groove of said first plurality of grooves.

A pair of motorcycle tyres, each motorcycle tyre of said pair of motorcycle tyres comprising a tread band comprising a central portion and two shoulder portions arranged at axially opposite sides of the central portion, wherein:

• the central portion comprises a first plurality of grooves extended according to a substantially longitudinal direction and alternatively arranged at opposite sides of an equatorial plane of said tyre, wherein each groove of said first plurality of grooves has a substantially curvilinear course such as to form a concavity;
• the central portion comprises a sub-portion substantially free of grooves placed astride an equatorial plane of said tyre;
• and
• each of said shoulder portions comprises a second plurality of grooves arranged obliquely relative to the equatorial plane of said tyre,
• the pair of motorcycle tyres comprising a first tyre wherein the concavity of the grooves of said first plurality of grooves is directed toward the equatorial plane of said tyre capable of being adapted for mounting on a rear wheel of said motorcycle;
• and a second tyre wherein the concavity of the grooves of said first plurality of grooves is directed according to a direction opposite to the equatorial plane of said tyre capable of being adapted for mounting on a front wheel of said motorcycle.

A pair of motorcycle tyres, each motorcycle tyre of said pair of motorcycle tyres comprising a tread band comprising a central portion and two shoulder portions arranged at axially opposite sides of the central portion, wherein:

• the central portion comprises a first plurality of grooves extended according to a substantially longitudinal direction and alternatively arranged at opposite sides of an equatorial plane of said tyre, wherein each groove of said first plurality of grooves has a substantially curvilinear course such as to form a concavity;
• the central portion comprises a sub-portion substantially free of grooves placed astride an equatorial plane of said tyre;
• and
• each of said shoulder portions comprises a second plurality of grooves arranged obliquely relative to the equatorial plane of said tyre,
• wherein the grooves of said second plurality of grooves have a substantially curvilinear course thereby forming a concavity,
• the pair of motorcycle tyres comprising a first tyre wherein the concavity of the grooves of said second plurality of grooves is directed according to a direction opposite to a preferred rolling direction of said tyre, capable of being adapted for mounting on a rear wheel of said motorcycle;
• and a second tyre wherein the concavity of the grooves of said second plurality of grooves is directed according to a preferred rolling direction of said tyre, capable of being adapted for mounting on a rear wheel of said motorcycle.

A pair of motorcycle tyres, each motorcycle tyre of said pair of motorcycle tyres comprising a tread band comprising a central portion and two shoulder portions arranged at axially opposite sides of the central portion, wherein:

• the central portion comprises a sub-portion substantially free of grooves placed astride an equatorial plane of said tyre;
• and
• each of said shoulder portions comprises a second plurality of grooves arranged obliquely relative to the equatorial plane of said tyre,
• wherein the grooves of said second plurality of grooves have a substantially curvilinear course thereby forming a concavity,
• the pair of motorcycle tyres comprising a first tyre wherein the concavity of the grooves of said second plurality of grooves is directed according to a direction opposite to a preferred rolling direction of said tyre, and wherein the concavity of the grooves of said first plurality of grooves is directed toward the equatorial plane of said tyre capable of being adapted for mounting on a rear wheel of said motorcycle;
• and a second tyre wherein the concavity of the grooves of said second plurality of grooves is directed according to a preferred rolling direction of said tyre, and wherein the concavity of the grooves of said first plurality of grooves is directed toward the equatorial plane of said tyre capable of being adapted for mounting on a front wheel of said motorcycle.
