Indoor tire durability test method

摘要

PPROBLEM TO BE SOLVED: To provide an indoor tire durability testing method capable of reproducing and accurately evaluating tire failures on the market, using an indoor tire durability machine. PSOLUTION: By measuring tire's inner temperature for an arbitrary tire at in-vehicle commercial running and then making a tire T actually having the same structure with the above tire running on a condition equivalent to the speed loading condition at the commercial running using an indoor tire durability testing machine, the method conducts a tire durability test under a condition with the tire's inner temperature at the indoor test meeting that at the commercial running by decreasing the testing temperature in a temperature-controlled room 2 at that time even to a temperature below that at the commercial running.
