Tyre for vehicle wheels having improved tread pattern

A tyre for a vehicle wheel comprising a tread having a tread pattern, said tread being separable by an equatorial plane of said tyre in a first half and in a second half, said first half of said tread comprising a first shoulder portion of said tread, said second half of said tread comprising a second shoulder portion of said tread, wherein said tread pattern comprises a sequence of substantially identical modules of grooves circumferentially disposed along said tread, each of said modules comprising:

• a) a first slanted transverse groove extending from said first shoulder portion of said tread to a first end, said first slanted transverse groove crossing said equatorial plane so that said first end is located in said second half of said tread;
• b) a second slanted transverse groove extending from said second shoulder portion of said tread to a second end,
• said second slanted transverse groove crossing said equatorial plane so that said second end is located in said first half of said tread;
• c) a third slanted transverse groove extending from said first shoulder portion of said tread to a third end located in said first half of said tread;
• and
• d) a fourth slanted transverse groove extending from said second shoulder portion of said tread to a fourth end located in said second half of said tread,
• wherein:
• e) said first end is substantially located at an intermediate portion of said second slanted transverse groove;
• and
• f) said second end is substantially located at an intermediate portion of a first slanted transverse groove of a circumferentially adjacent module.
