PROBLEM TO BE SOLVED: To provide a pneumatic tire for emergency improved in ozone resistance and weather resistance, while maintaining light weight. SOLUTION: In this tire, thickness of a tread 1 is reduced as compared with that in a normal tire. The tread 1 is made by blending more than 1 pts.wt. of p-phenylenediamine system antioxidant in relation to rubber 100 pts.wt. A rubber sheet layer at the inside of the tread 1 is made by increasing p-phenylenediamine system antioxidant by 1 pts.wt. in relation to rubber 100 pts.wt. and blending p-phenylenediamine system antioxidant more than that in the tread 1.
