Abstract
A pneumatic tire for large size and high speed motor cycles is disclosed. The tire comprises a tread having a rib-block pattern defined by a central groove extending in a substantially circumferential direction of the tire at a center of a crown, a first circumferential groove adjacent to the central groove, a second circumferential groove arranged at that side of the first circumferential groove opposite to the central groove, which consists of a common portion united with the first circumferential groove and a non-common portion arranged circumferentially in a discontinuous manner independently of the common portion, and long and short transverse grooves arranged within regions located between the common portion and the tread edge on the one hand and between the non-common portion and the tread edge on the other hand.
