摘要

PROBLEM TO BE SOLVED: To provide a testing technique and testing equipment of a pneumatic tire capable of reproducing efficiently wire creases of belt layer of tread and groove cracks generated in markets and evaluating durability of tires. SOLUTION: On a test road 2 with an extended split-level 5, the tire 1 under test that is made to a predetermined inner pressure through a rim combination is deployed so that the split-level 5 is located within a tread groove and letting the tread to connect to ground on an upper side roadbed 4 of the test road 2 by loading a predetermined burden to roll to the extended direction of split-level 5.
