Abstract

A method for testing a punctured tyre's resistance to a loss in pressure includes: creating a plurality of punctures in a wall of the tyre by inserting a plurality of puncturing objects through the wall; running the tyre with the puncturing objects in the wall thereof over a given distance with a regulated inflation pressure; stopping the running of the tyre; and determining, for each puncture, a pressure loss resistance index based on an estimate of a leak rate of the puncture.
