text: Known as the pneumatic tire for solving problems described above is, for example, a pneumatic tire (refer to, for example, patent document 1) comprising: a non-conductive tread whose outer surface is a tread surface; a conductive undertread which is positioned in an inside of the tread in a radial direction; a conductive penetration part which penetrates through the tread described above and which is exposed on the tread surface at one end thereof and comes to the undertread described above at the other end; a pair of non-conductive side walls which each extend approximately inward in a radial direction from the end of the tread; a pair of conductive clinches which each extend approximately inward in a radial direction from the ends of the side walls; a pair of beads which are positioned insider than the clinch in an axial direction; a carcass bridged between one bead and the other bead along the insides of the tread and the side wall; and a conductive reinforcing layer which is laminated on the carcass described above in an inside of the undertread in a radial direction, wherein the carcass described above has a lot of cords aligned in parallel and a conductive topping rubber, and the carcass has an electric resistance Rc of less than 1.0×108Ω represented by a specific equation.
