Zusammenfassung:	Provided is a pneumatic tire whose safety factor and durability are improved without generating a problem of an increase in the weight of a tire and an increase in the inner surface cord protrusion failure. Provided is a pneumatic tire including one or more carcasses 2 extending toroidally between bead cores 1 embedded in a pair of bead portions 11 respectively. A polyester fiber cord whose total decitex as a twisted cord is 4300 to 5100 dtex, whose cord strength as a dip treated cord is 6.5 to 7.2 cN/dtex and whose cord elongation at a stress loading of 2 cN/dtex is 3.5 to 4.0% is used as a reinforcing cord of the carcass 2, and the tenacity of a treat which is the reinforcing cord covered with rubber per unit width is 2.9 to 3.2 kN/cm.
