PURPOSE:To improve antislip effect by forming blocks on the tread of a tire, forming in exposed state respective moisture adsorbing elements due to a capillary phenomenon and a structure element having air bags on the tread of each block, and forming a configuration element having slant surfaces in front and rear of the block. CONSTITUTION:There are provided first patterns 1 comprising at least two kinds of blocks A, B on both sides in the width direction of a tire and a second pattern 2 comprising at least two kinds of blocks C, D. The block A is constructed by a structure element consisting of a trapezoid projection portion 10, slant surfaces 11, 12 in front and rear of section, cut grooves 21 and air bags 22, and adsorbing element having cut grooves 31 formed on a projection face 14 and a central core 32 projecting into the air bag 22 in a radial direction outwards. Blockes B, C, D are constructed as shown in figures by three elements consisting of a configuration element, the structure element and the adsorbing element similar to the block A. According to this constitution, antislip effect can be improved. |
