    摘要: Provided are an adhesive sheet for a tire, which has a small ratio of dimensional change with the passage of storage time or the like even in a case in which a polyolefin-based resin film is used as a substrate; and a method for manufacturing an adhesive sheet for a tire.
    Disclosed is an adhesive sheet for a tire, the adhesive sheet including a substrate and an adhesive layer, and the adhesive layer containing a hot melt type adhesive composition, characterized in that the ratio of dimensional change in the MD direction of the adhesive sheet for a tire measured for 7 days at 60°C according to JIS K 7133 has a value of below ±0.6%, the substrate is a polyolefin-based resin film, the hot melt type adhesive composition includes the following components (A) to (C):
    (A) a block copolymer: 15% to 40% by weight;
    (B) plural tackifiers having different softening points: 30% to 70% by weight; and
    (C) a liquid hydrocarbon-based plasticizer: 10% to 50% by weight, and
    the number average molecular weight of the (C) liquid hydrocarbon-based plasticizer has a value within the range of 10,000 to 60,000.
