Abstract
Official abstract text for this publication.
A heavy duty tire comprises a tread portion provided with belt plies and circumferentially-extending main grooves, wherein a shoulder rib area between the axially outermost shoulder main groove and a tread edge is subdivided by a sub groove into an axially inner main rib zone and an axially outer sub rib zone. The main rib zone is provided with a high elastic modulus rubber layer extending along the axially outer edge of the main rib zone to form a part of the tread face and made of rubber having an elastic-modulus higher than that of rubber forming the tread face except for said part of the tread face. The axial width (W 1 a ) of the high elastic modulus rubber layer is 0.3 to 0.6 times the axial width (W 1 ) of the main rib zone.
