TYRE FOR PASSENGER VEHICLE

A tire (1) for a passenger vehicle exhibits improved performance in terms of rolling resistance without adversely affecting the transverse cornering stiffness. The bead (50) is made more flexible by the use of low-hysteresis materials. The transverse cornering stiffness is increased by managing the contact between the bead (50) and the mounting rim (100). In a first section located in the contact patch, in at least a first bead, the length of the rim contact curve, LADC, is measured. In a second section located opposite the contact patch in relation to the axis of rotation of the tire, in at least a second bead, the length of the rim contact curve, LCJ, is measured. The ratio of the difference in the lengths of the rim contact curves in the two sections, i.e. 100*(LADC−LCJ)/LCJ, is greater than or equal to 30.
