A passenger vehicle tire having rolling resistance without negatively affecting the grip and behaviour. The tread (2) has a radial height HS between 5 mm and 8 mm, a volumetric void ratio TEV between 22% and 30%, a total volume VCP of the main voids (241) at least equal to 80% of the total volume VC of the voids (24), and comprises an elastomeric compound having a glass transition temperature Tg between 22° C. and 5° C., a Shore A hardness between 45 and 65, and a dynamic loss tgδ at 23° C. at least equal to 0.13 and at most equal to 0.39. The metal reinforcers of the working layers (41, 42) are steel monofilaments having a cross section S with a smallest dimension Dmin between 0.20 mm and 0.50 mm. The monofilaments distributed at a density dT between 100 threads/dm 200 threads/dm, each working layer (41, 42) having a mean radial thickness ET between D+0.1 mm and D+0.6 mm.
