ABSTRACT:
An off-road motorcycle tire having a block pattern comprising a plurality of blocks11defined by tread grooves10, each block11having a circumferential profile16of top surface12in the form of a straight line or a circular arc having a radius Ra of curvature of at least 500 mm, in which the circumferential profile denotes a profile in the circumferential section which passes through the centroid G of the top surface12and is parallel to the tire equatorial plane Cc. According to the invention, the ground contact pressure at the periphery of the top surface of blocks11is prevented from lowering to enhance the edge effect.
