To provide a system capable of predicting a residual life of a case of a tire.
A tire case life prediction system predicting a residual life of a case includes: tire condition measurement means measuring a characteristic value including at least tire internal pressure information indicating a tire condition or a vehicle travel condition; temperature history estimation means 32 estimating a temperature history of at least one part inside the case based on the characteristic value measured by the tire condition measurement means; member physical property presumption means 33 presuming at least one present physical value about at least one case constituent member being able to deteriorate caused by an in-tire air temperature based on at least the temperature history estimated by the temperature history estimation means and the tire internal pressure information; and residual runnable distance prediction means 34 predicting a runnable distance of a tire until the present physical value presumed by the member physical value presumption means reaches a preset limit physical value.
