PURPOSE:To enhance the durability of a marker against the rubbing by curbstones, by constituting the marker with a bright color rubber composition having a predetermined blending, an age resistor shift shielding film and a bonding layer, and as well by arranging the thus constituted marker in a recessed part formed in the side wall section of a tire. CONSTITUTION:A recessed section 7 in a side wall is fitted therein with a marker consisting of a bright color rubber composition layer 2 having a thickness of 0.1-1.5mm. and containing more than 30pts.wt. of at least either one of chloroprene rubber and chlorosulfonated polyethylene in 100pts.wt. of rubber component, an age-resistor shift shielding layer 4 having a thickness of 3mum-10mum and made of material selected from the group consisting of polyester film, vinylidenechrolide-vinylchloride polymer film and nylon film, and a bonding layer 3 having a thickness to 0.005-0.5mm. and made of material selected from a group consisting of thermoplastic polyester and thermoplastic polyuretane. With this arrangement, the durability of the marker is enhanced against the rubbing by curbstones. |
