The invention relates to a passenger vehicle tyre (1) and aims to improve the trade-off between rolling resistance and antagonistic performance such as the various types of grip (longitudinal/transversal, on dry/wet ground) and behaviour. For a tread (2) comprising raised elements (22) having a radial height HS at most equal to 8 mm, and having a volume groove ratio TEV of 22% to 30%, according to the invention, the radial height HS of the raised elements (22) of the tread (2) is at least equal to 5.0 mm, the total volume VCP of all the main recesses (241) in the tread (2) is at least 80% of the total volume VC of the recesses (24) in the tread (2), and the at least one elastomeric compound constituting the tread (2) has a glass transition temperature Tg of -22°C to -5° C, a Shore A hardness of 45 to 65 and a dynamic loss tgδ at 23°C of 0.13 to 0.39.
