The invention aims to improve the grip of a passenger tyre (1), without degrading the behaviour, wear and endurance thereof and while decreasing the weight. According to the invention, the tread (2) has a volumetric void ratio VVR at least equal to 20% and at most equal to 29% and a ¾ radial height at least equal to 6.0 mm and at most equal to 7.6 mm, and comprises an elastomeric mixture having a glass transition temperature Tg at least equal to -18°C and at most equal to -6°C, a Shore A hardness at least equal to 60 and at most equal to 75 and a loss at 60°C at least equal to 24%> and at most equal to 35%>. Finally, the metal reinforcers of the working layers (41, 42) are steel monofilaments having a section S with the smallest dimension Dmin thereof at least equal to 0.20 mm and at most equal to 0.50 mm, distributed according to a density di at least equal to 100 threads/dm and at most equal to 200 threads/dm, each working layer (41, 42) having a mean radial thickness ET at least equal to D+0.1 mm and at most equal to D+0.6 mm, with D the diameter of the circle delimited by the section S of the reinforcer.
