Method for controlling the footprint area of a tyre and tyre for vehicle wheels

A tyre for motor-vehicle wheels, comprising:

• a carcass structure comprising a pair of beads having a same radial distance from a rotation axis of the tyre;
• and
• a tread band disposed at a radially external position with respect to the carcass structure,
• wherein, in each radial half-section of the tyre, the tread band is symmetric relative to a symmetry axis thereof, and
• wherein, in each radial half-section, a medium line of the tread band and the rotation axis of the tyre form a predetermined angle different from zero.

A process for manufacturing tyres for motor-vehicle wheels, comprising:

• building a green tyre comprising at least one carcass structure having a pair of beads and a tread band disposed at a radially external position with respect to the carcass structure,
• wherein any transverse half-section of said green tyre has an outer profile that is symmetric to a mid-line plane thereof;
• and
• vulcanising and moulding said green tyre,
• wherein, during the vulcanising and moulding, said tyre is deformed until a predetermined angle different from zero is formed between any medium line of the tread band and a rotation axis of a vulcanised and moulded tyre.

A wheel for motor-vehicles, comprising:

• a rim comprising two housings for beads having a same radial distance from a rotation axis of the wheel;
• and
• a tyre mounted on the rim inflated to an operating pressure and comprising a tread band,
• wherein, in each radial half-section of the wheel, the tread band is symmetric relative to a symmetry axis thereof, and
• wherein, in each radial half-section, a medium line of the tread band and the rotation axis of the wheel form a predetermined angle different from zero.
