Tire comprising hybrid transverse cuts

A tire for a passenger vehicle, the tire comprising a tread intended to come into contact with a ground when the tire is running, via a tread surface, the tread comprising:

• main circumferential cuts having depths greater than or equal to 50% of a tread-pattern height, comprising first and second axially outer main circumferential cuts arranged axially on either side of a mid-plane of the tire, the first and second axially outer main circumferential cuts being axially outermost main circumferential cuts of the tread;
• a first axially lateral portion arranged axially outside the first axially outer main circumferential cut and extending axially from a first axial edge of the tread surface to the first axially outer main circumferential cut;
• and
• a second axially lateral portion arranged axially outside the second axially outer main circumferential cut and extending axially from a second axial edge of the tread surface to the second axially outer main circumferential cut,
• the tire comprising a tread layer and a supporting layer of the tread layer, the supporting layer being arranged radially inside the tread layer,
• wherein the tread comprises hybrid transverse cuts made at least partially in at least one of the first and second axially lateral portions, each hybrid transverse cut comprising:
• a narrow axially inner portion having, at a bottom of the hybrid transverse cut, a width ranging from 0.2 mm to 0.6 mm, the narrow axially inner portion being an axially innermost portion of the hybrid transverse cut in the at least one of the first and second axially lateral portions;
• and
• a wide axially outer portion having, at the bottom of the hybrid transverse cut, a width ranging from 0.7 mm to 5.0 mm, communicating with the narrow axially inner portion, arranged axially outside the narrow axially inner portion, the wide axially outer portion being an axially outermost portion of the hybrid transverse cut in the at least one of the first and second axially lateral portions,
• wherein each hybrid transverse cut has a hybrid transverse cut bottom, an entire bottom of each hybrid transverse cut being arranged radially outside an interface between the tread layer and the supporting layer,
• wherein the wide axially outer portion has a mean radial distance dem between the bottom of the wide axially outer portion and the interface,
• wherein at least 60% of a curvilinear length of a bottom of the narrow axially inner portion has a radial distance from the interface strictly greater than the mean radial distance dem, and
• wherein the mean radial distance dem ranges from 0.3 mm to 1.0 mm.
