<p>A motorcycle tyre in which the tread surface (2A) is curved convexly so that the maximum cross-section width of the tyre lies between axial edges of the tread portion (2), and the belt (7) comprises at least three plies (10,11,12), wherein the radially inner ply (10) and radially outer ply (12) are made of the same strip of rubberised parallel cords having a strip width of from 85 to 105 % the tread width (TW), and the middle ply (11) is made of a strip of rubberised cords having a strip width which is different from that of the inner and outer plies (10,12), whereby an increase in the number of strip supplying units in a tyre building apparatus can be avoided without decreasing tyre performance. <IMAGE></p> |
