  "textContent": "Vehicle pneumatic tire of radial construction with a radial carcass (3), a multi-layer belt structure (2) and a tread (1), which has in the profiled region a tread part (7) composed of a radially outer rubber layer (9), whose thickness increases continuously in the direction of the tire apex, and a radially inner rubber layer (10), whereby the outer rubber layer (9) has lower rebound resilience than the inner rubber layer (10), which extends on the shoulder side beyond the width (B) of the tread (1) in the ground contact area. The radially outer rubber layer (9) also extends on the shoulder side beyond the width (B) of the tread (1) in the ground contact area, whereby the volume of the outer rubber layer (9) in shoulder-side sections (11), whose width (bl) amounts to 15% to 25% of the width (B) of the tread (1) in the ground contact area, accounts for between 20% and 30% of the volume of the tread part (7) in these sections (11), and whereby the volume of the radially outer rubber layer (9) in the central section (12) extending between the shoulder-side sections (11) accounts for 30% to 50% of the volume of the tread part (7) in this section (12).",
