Abstract
A load derivation method includes: a distance measurement step of measuring, by a displacement meter attached to a rim, a distance from the displacement meter to an inner surface of a tire; an internal pressure measurement step of measuring an internal pressure of the tire, by a sensor attached in a chamber of the tire; and a load derivation step of deriving, by a derivation section, a load on the tire during running, based on the measured distance and the measured internal pressure.

A tire life prediction method comprising:
- measuring, by a displacement meter attached to a rim, a distance from the displacement meter to an inner surface of a tire;
- measuring an internal pressure of the tire, by a sensor attached in a chamber of the tire;
- deriving, by a derivation section, a load on the tire during running, based on the measured distance and the measured internal pressure,
- predicting a tire life by a determination section based on the load derived based on the measured distance and the measured internal pressure,
- wherein the displacement meter is attached on or in a hole of a rim base portion.
