WIPO Patent Application WO/2019/111974
Kind Code:
A1
Abstract:
In this pneumatic tire, a puncture prevention member is adhered to at least a portion of the inside surface of a tire main body. When M (MPa) is the 100% modulus of the portion of the puncture prevention member that has the lowest 100% modulus, T (mm) is the thickness of said portion of the puncture prevention member, Y (N/mm) is the initial stiffness when a nail penetrates, and S (N) is the perforation strength of the portion of the puncture prevention member that has the highest perforation strength, the following relational expressions are satisfied: S≥100×M×T+4.5, and Y/(M×T)≥2.
