Claim:
A pneumatic tire comprising: bead units which include an inside bead core and an inside bead filler located in an inside under an equipment on a vehicle, and an outside bead core and an outside bead filler located in an outside under the equipment on the vehicle; and a carcass layer which includes a main body extending from the inside bead core to the outside bead core and turnbacks each of which is turned back from the inside bead core or the outside bead core to an internal side of a belt layer, wherein: each edge of the turnbacks provided at a tire inner peripheral side of the belt layer is located inside from each edge of the belt layer in a tread width direction, a height of the outside bead filler is lower than a height of the inside bead filler in a cross section along the tread width direction, the bead units further includes an inside bead toe and an outside bead toe, the height of the inside bead filler is set within 20 to 50% of a tire height in the cross section along the tread width direction, the tire height being a distance from a bead line connecting between the inside bead toe and the outside bead toe to a most outward peripheral position on the tread, an outside maximum width from a tire central line passing a center of the bead line is wider than an inside maximum width in the cross section along the tread width direction a height position providing the outside maximum width is higher from the bead line than a height position providing the inside maximum width, and a first inner average radius of an internal outline in the tire outer peripheral side from a position providing the inside maximum width, is larger than a second inner average radius of an internal outline in the tire inner peripheral side from the position providing the inside maximum width.
