Abstract
Provided is a pressure sensitive adhesive sheet for tires that enables continuous and efficient labeling on tires using a labeling apparatus. The pressure sensitive adhesive sheet includes a release material (C), a first pressure sensitive adhesive layer (B1), a first substrate (A1), a second pressure sensitive adhesive layer (B2), and a second substrate (A2), in this order, and satisfies Requirement (1): in a planar view of the pressure sensitive adhesive sheet, the outline of the first pressure sensitive adhesive layer (B1) exists inside the outline of the second substrate (A2); and Requirement (2): the MD stiffness of the second substrate (A2), measured in the Gurley method according to JIS L 1085, is 0.10 mN or more.
