Pneumatic Tire with Optimized Crown-and-Tread-Pattern Architecture
The invention is a tire comprising a crown comprising at least one layer of reinforcing elements. The radially outermost layer comprises at least one undulation (512). The undulations (512) in the radially outermost layer (5) are such that the points of the undulations are radially on the outside of...

| description | The invention is a tire comprising a crown comprising at least one layer of reinforcing elements. The radially outermost layer comprises at least one undulation (512). The undulations (512) in the radially outermost layer (5) are such that the points of the undulations are radially on the outside of the points of said layer (5) that are vertically beneath the centre of the bottom face (243) of the closest major groove (24) by at least a radial distance of 1.5 mm. The undulations (512) in the radially outermost crown layer make up at least 10% of the radially outer surface (ROS) of said crown layer (5). A rubber compound with a dynamic modulus G*, measured at 40° C. at 10% peak-to-peak strain at 10 Hz, that is at most equal to 3.25 MPa, makes up at least 30% of the rubber compounds vertically above said undulations. |
