PROBLEM TO BE SOLVED: To improve durability of a tire which is capable of controlling degradation of a ride quality in a normal traveling, and capable of performing run-flat travel.SOLUTION: A tire 100 includes a carcass 5 leading from a tread portion 4 to a bead portion 2, and a reinforced rubber layer 10 arranged on a tire inner surface side of the carcass. The reinforced rubber layer 10 includes a first rubber portion 11, and a second rubber portion 12 with a modulus of elasticity being lower than that of the first rubber portion 11. A thickness T1 of the first rubber portion 11 at a height position P3 where a tire width is maximum in a cross section in a tire width direction is 40-60% of the thickness T0 of the reinforced rubber layer 10. |
