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) comprises a filler layer (70) and a lateral reinforcing layer (60) 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, i.e. 100*(LADC−LCJ)/LCJ, is greater than or equal to 30.
