Abstract
PURPOSE:To prevent lopsided abrasion without impairing characteristics for snow by forming at least 60% the blocks on the tread face of a pneumatic tire with a block having connected grooves of specific dimensions. CONSTITUTION:A pneumatic tire has blocks 3 each having connected grooves 4 on its surface and these blocks 3 occupy at least 60% the whole blocks on a tread pattern. In the connected grooves 4, the inside interval L1 between grooves running in the radial direction of tire is smaller than the inside interval L2 between grooves running in the rotating direction of tire. Also, the width (a) of the grooves running in the circumferential direction of tire is smaller than the width (b) of the grooves running in the radial direction of tire. Thus, by forming at least 60% the blocks on a tire tread face with a block 3 having connected grooves, excellent characteristics for snow can be obtained, improving driving stability while preventing lopsided abrasion caused by connected grooves.
