A pneumatic tire capable of improving run-flat durability is provided. SOLUTION: The rubber component contains 55 parts by mass or more of carbon black with respect to 100 parts by mass, and the physical properties of vulcanized rubber have an elastic modulus at 100% elongation (M100) of 10 MPa or more and a tangent loss tan δ of 28 to A pneumatic safety tire in which a rubber composition having a Σ value at 150 ° C. of 6.0 or less is used, and a cord constituting the carcass layer is a polyethylene naphthalate fiber cord. The carbon black is preferably at least one selected from the group consisting of FEF grade, FF grade, HAF grade, ISAF grade and SAF grade. [Selection] Figure 1 |
