To provide a pneumatic tire 2 which makes a carcass coad unlikely to be creased or exposed, and is superior in steering stability.
The carcass 10 comprises a first ply 26, and a second ply 28. The first ply 26 is folded from the inside to the outside in an axial direction around a core 22. By this folding, a main part 30 and a pair of folded parts 32 are formed in the first ply 26. The second ply 28 is overlapped with the folded parts 32 in the vicinity of an end 34. The first ply 26 comprises a number of parallel first coads, and a topping rubber. The second ply 28 comprises a number of parallel second coads, and the topping rubber. The first coad comprises aramid fibers. The second coad comprises nylon fibers. Heat shrinkage percentage of the second coad is larger than that of the first coad.
