Assembly of tire and rim
First Claim
1. A tire-rim assembly, characterized in that a great number of substantially sphere-shaped particles each consisting of a continuous phase of a resin and a closed cell(s) and having a mean bulk specific gravity of not more than 0.1 are disposed in an interior defined by assembling a hollow doughnut-shaped tire onto an approved rim, and a pressure at 25°
- C. in the interior of the tire is not less than 150 kPa as an absolute pressure.

Abstract
There is provided a tire-rim assembly capable of stably running over a distance required even in the dropping of the tire internal pressure after the injuring of the tire without sacrificing rolling resistance and ride comfort in the usual running before the injuring of the tire, wherein a great number of substantially sphere-shaped particles each consisting of a continuous phase of a resin and a closed cell(s) and having a mean bulk specific gravity of not more than 0.1 are disposed in an interior defined by assembling a hollow doughnut-shaped tire onto an approved rim, and a pressure at 25° C. in the interior of the tire is not less than 150 kPa as an absolute pressure.

- 40. A tire-rim assembly comprising a closed space defined by a tire and a rim and a compressed gas filled in the space and having means for detecting a change of a pressure in the gas and means for approaching an inner volume of the closed space changed by the pressure change to a volume before the change.
- 47. A method of applying an internal pressure to a tire-rim assembly formed by mounting a hollow doughnut-shaped tire onto an approved rim and provided with means for detecting a change of pressure of a gas in an interior defined by the tire and the rim, characterized in that a great number of substantially sphere-shaped particles each comprising a continuous phase made of a resin and a closed cell(s) held at a pressure higher than an atmospheric pressure are filled in the interior of the assembly to apply a given internal pressure to the assembly.
- 49. An apparatus for applying an internal pressure to a tire-rim assembly formed by mounting a hollow doughnut-shaped tire onto an approved rim, comprising a storage means for storing substantially sphere-shaped particles each comprising a continuous phase made of a resin and a closed cell(s) held at a pressure higher than an atmospheric pressure, and a transportation means for transporting stored particles to an interior of the assembly.

54. A method of supplying a tire-rim assembly formed by disposing a great number of substantially sphere-shaped particles each comprising a continuous phase made of a resin and a closed cell(s) held at a pressure higher than an atmospheric pressure in an interior of a hollow doughnut-shaped tire and an approved rim assembly, characterized in that the interior of the assembly filled with the particles is adjusted to a given pressure at a step of transporting the assembly filled with the particles to a delivery side.
- 55. A method of providing a service after the supply of a tire-rim assembly for a driver possessing a vehicle mounted with tire-rim assemblies each having a great number of substantially sphere-shaped particles each comprised of a continuous phase of a resin and a closed cell(s) held at a pressure higher than an atmospheric pressure disposed in an interior of an assembly of a hollow doughnut-shaped tire and an approved rim, characterized in that an end equipment capable of conducting communications is arranged on the vehicle and means for detecting a change of pressure is arranged on the assembly, and when the detecting means detects an accident, a particular information from the detecting means is transmitted from the end equipment through a communication control section to an information control server having a data base section previously stored with a position information of service shops for selling and repairing the tire-rim assemblies, and the information control server picks up an information of service shops in an area positioning the vehicle from the data base section based on the received particular information and transmits the picked service shop information and an internal pressure abnormal alarm through the communication control section to the end equipment, and the internal pressure abnormal alarm and service shop information received in the end equipment are informed to the driver in the vehicle.
