Abstract
A heavy duty tire comprises a pair of axially outermost circumferential rows of shoulder blocks, each of the shoulder blocks provided with a circumferentially extending narrow groove, the narrow groove subdividing the shoulder block into an axially inner wide main part and an axially outer narrow lateral part, and the narrow groove is curved convexly so that the narrow lateral part is narrower in a middle region than both the circumferential end regions, whereby the heel and toe wear and shoulder wear and resistance to tear-off can be improved.
