PNEUMATIC TIRE-TESTING METHOD AND TESTER

摘要

PROBLEM TO BE SOLVED: To provide a pneumatic tire-testing method and a tester for efficiently reproducing tearing similar to the tearing of a tread coming into existence in the market and evaluating tear resistance of a tire. SOLUTION: A test tire 1 combined with a rim is given a prescribed inner pressure. Prescribed load is loaded thereon to bring a tread into contact with a planar surface of a mounting table. A rod-like projection 2 fixed on the surface of the mounting table is brought to a state where it is covered with a circumferential groove 1b of the test tire 1 extending over a grounding area with the mounting table for the test tire 1 and a non-grounding area. The mounting table is turned centering around a rotation axis P substantially coinciding with a direction normal to the surface thereof to give an external force to a rib 1a by means of the rod-like projection 2.
