TYRE AND TREAD THEREOF

摘要

The description relates to a tread for tyres, comprising on each side of the equatorial plane a row of central blocks and a row of intermediate blocks between a central longitudinal groove and a pair of longitudinal lateral grooves. The blocks of the central rows are separated from the blocks of the intermediate rows by a pair of circumferential sipes and the blocks of the central and intermediate rows are circumferentially spaced by a plurality of very deep transverse grooves. The pattern of the tread comprises blocks of the intermediate rows which are circumferentially staggered relative to the blocks of the central rows and blocks of the central rows which are circumferentially staggered with respect to one another. The transverse grooves have centre lines which are inclined at an angle alpha in opposite directions to one another with respect to a plane perpendicular to the equatorial plane.
