Abstract:
1. A process for monitoring a tire condition and repairing a punctured pneumatic tire having a structure of controlling the damage of the tire produced by the unavoidable running in the punctured state in a tire-rim assembly which comprises: mounting on a vehicle an assembly of a pneumatic tire and an approved rim provided with means for raising an internal pressure alarm, said pneumatic tire comprising a carcass of at least one ply toroidally extending from a pair of bead portions to a tread portion through a pair of sidewall portions, a belt of at least one belt layer arranged on an outer circumference of a crown portion of the carcass, and an auxiliary load-supporting structure satisfying a requirement that a deformation quantity of the tire in a radial direction thereof at a rim-assembled state under a load corresponding to 90% of a maximum load capacity at an internal tire pressure of zero is within a range of 30-60% of a section height of the tire under no load at the internal tire pressure of zero; detecting a puncture of the tire produced during the running of the tire by the means for raising an internal pressure alarm; unavoidably running the punctured tire to a relatively short-range safe place to quickly stop the vehicle; and refilling gas inside the tire, which is emitted due to the puncture, to a given internal pressure by a gas filling means equipped on the vehicle while occluding a punctured hole with a puncture repairing means equipped on the vehicle; and wherein the auxiliary load-supporting structure is constructed so as not to at least contact inner surface parts located at the same sidewall portion with each other even in the unavoidable running at the puncture state.
