Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent generation of a crack on the surface of a buttress caused by aging of rubber. SOLUTION: This tire has a SOT structure in which side wall rubber 3G is extended up to a buttress part 10 to cover an outer end part of tread rubber 2G. The ratio of Ts/T of thickness Ts of the side wall rubber 3G on a line J connecting contacts of a circle K in contact with a radial direction intermediate position P of the surface 10S of the buttress part 10 and a tire inner cavity face HS and total thickness T between the contacts is made 1/2 to 2/3. The side wall rubber 3G is made to have rubber hardness (durometer A hardness) of 50 to 57° and loss tangent tanδ of 0.10 to 0.20. COPYRIGHT: (C)2004,JPO
