The invention relates to a tyre (1) for a passenger vehicle of which the performance in terms of rolling resistance has been improved without adversely affecting the transverse slip stiffness. The bead (50) is made more flexible by the use of low-hysteresis materials. The transverse slip stiffness is compensated for through the use of a rigid, low-hysteresis sidewall layer (30). The layers of compounds of the lower region having a viscoelastic loss Tan(δ)max less than or equal to 0.10 represent a volume of between 30% and 90% of the total volume of said lower region, and the elastic shear modulus G′ (M3) of each sidewall layer is in the range [0.5; 10] MPa.
