PURPOSE:To improve comfortableness to drive, flat spot or the like by forming the captioned tire, which has a carcass with fiber cords of predetermined extension arranged at a predetermined angle, through burying soft rubber of predetermined hardness between the carcass and the tread. CONSTITUTION:Soft rubber 15 of JIS hardness 40-50 deg. is buried covering the whole area of a tread part 2 between a carcass 5 and a tread 2 of a bias tire equipped with the carcass 5 formed by arranging the plural number of plies, formed by arranging fiber cords with a constant load extension 3-8% according to JIS L1017 provisions at angles of 40-50 deg. with respect to the circumferential direction of the tire, in such a manner as the cords cross with each other between plies. THe width WR of this soft rubber in this case is limited to 90- 110% of the width WT of the tread. Comfortableness to drive, flat spot or the like can be improved due to this structure. |
