Abstract
A sealing tube is wrapped around the rim and inflated such as to seal the gap between tire and rim if the seal between the tire bead and rim has lost its integrity. After this, the tire can be inflated to specified pressure at a slow rate using a portable compressor. The repair can be done at roadside on any vehicle using inflatable tires usually without demounting the wheel or even jacking up the defective wheel.
Claims12
A method for roadside repair for restoring tire bead integrity of a tire having an inner circumferential bead edge, in combination with a motor vehicle having a set of wheel rims and tires inflatable over and attached thereto, said tire being inflatable over a corresponding bead edge of a vehicle rim, said method comprising the steps of:
- fitting a linearly extending and cylindrical sealing tube with a sealed closed end and an open end around a periphery of the corresponding bead edge of said vehicle rim adjacent to the tire wall near said bead;
- said sealing tube assuming a crossection which is a circumferentially isotrophic cylindrical shape when inflated;
- crossing respective ends of the sealing tube over each other;
- inflating said sealing tube through a tire inflation valve spaced apart and near said sealed closed end with a compressor such that the gap between rim and tire is sealed;
- said long narrow linearly extending flexible inflatable sealing tube assuming an isotrophic toroidal shape when fitted and wrapped around said rim;
- detaching said compressor from said sealing tube and inflating said tire after sealing and tire inflation to recommended pressure for the vehicle and pulling off said sealing tube from between said tire and said rim.
A method for restoring tire bead integrity in a tire on a vehicle in combination with a motor vehicle having a set of wheel rims and tires inflatable over and attached thereto, without removal of a wheel, comprising the steps of:
- while the tire and rim are still on said vehicle, fitting a first section of a long narrow flexible inflatable linearly extending and cylindrical sealing tube with a sealed closed end and an open end around said rim, between the rim and said tire adjacent the bead of said rim, said sealing tube assuming a crossection which is a circumferentially isotrophic cylindrical shape when inflated;
- said sealing tube being closed at one end and open at an opposite end, the closed end of said sealing tube exiting away from said rim, the open and closed ends of said sealing tube crossing each other, and an inflation valve extending from said sealing tube between the closed end of said sealing tube and where said sealing tube exits said rim;
- closing off the open end of said sealing tube;
- feeding compressed gas into said sealing tube through said inflation valve sufficient to close off and seal any gap between said rim and tire;
- then feeding said compressed gas into said tire until normal tire pressure is obtained;
- and
- resuming operation of said vehicle.
A method for restoring tire bead integrity in a tire for use with a vehicle having a wheel rim, comprising the steps of:
- fitting a first section of a long narrow flexible linearly extending and cylindrical inflatable sealing tube with a sealed closed end and an open end around said rim, between the rim and said tire adjacent the bead of said rim, said sealing tube being closed at one end and open at an opposite end, the closed end of said sealing tube exiting away from said rim, the open and closed ends of said sealing tube crossing each other, and an inflation valve located near and extending from said sealing tube between the closed end of said sealing tube and where said sealing tube exits said rim, near the closed end thereof;
- closing off the open end of said sealing tube;
- feeding compressed gas into said sealing tube through said inflation valve sufficient to close off and seal any gap between said rim and tire;
- then feeding said compressed gas into said tire until normal tire pressure is obtained.
