Abstract
The present invention is directed to a tire comprising a tread, a pair of bead portions, a pair of sidewalls, wherein each of the sidewalls extends from the tread towards a respective bead portion, at least one carcass ply, and one or more belt plies. Moreover, the tire comprises at least one rubber strip having an electrical volume resistivity lower than 108 ohm·cm, extending from a radially inner position of the tread and along one of the sidewalls towards the respective bead portion.
Claims20
A tire comprising a tread, a pair of bead portions, a pair of sidewalls, wherein each of the sidewalls extends from the tread to a respective bead portion, at least one carcass ply, and one or more belt plies arranged radially between the tread and the at least one carcass ply in a crown area of the tire,
- wherein the tread comprises a tread strip having an electrical volume resistivity lower than 108 ohm·cm and extending from a radially outer surface of the tread to a radially inner position of the tread, wherein said radially inner position is radially above the belt plies;
- and
- wherein the tire further comprises at least one rubber strip having an electrical volume resistivity lower than 108 ohm·cm and extending from a radially inner position of the tread strip along a radially inner side of the tread and along one of the sidewalls towards the respective bead portion.
A tire comprising a tread, a pair of bead portions, a pair of sidewalls, wherein each of the sidewalls extends from the tread to a respective bead portion, at least one carcass ply, and one or more belt plies arranged radially between the tread and the at least one carcass ply in a crown area of the tire,
- wherein the tread comprises a tread base layer having an electrical volume resistivity lower than 108 ohm·cm, and
- wherein the tire further comprises at least one rubber strip having an electrical volume resistivity lower than 108 ohm·cm and extending from a radially inner side of the tread base layer along an axially outer surface of the sidewall towards the respective bead portion.
