The inside carcass layer has each of both ends which is turned up from the tire inside to the outside in relation to right and left bead cores and disposed between a bead core upper end and a bead filler upper end. The outside carcass layer has both ends which are turned down to a position lower than a tire maximum width point, and there is a space between the bead filler upper end and the outside carcass layer ends. |
