Disclosed is a sealing device for tire retreading, comprising an outer sleeve conforming to the crown, the tire shoulder and the upper sidewall of a tire outer contour, the outer sleeve being provided with a valve thereon; a bottom enveloping piece, the bottom of the bottom enveloping piece contacts the tire bead part and is compressed against the tire bead or the lower sidewall by a compression device. The lateral part of the bottom enveloping piece closely contacts the tire sidewall. The lower part of the outer sleeve rests on the lateral part of the bottom enveloping piece. A compression device is disposed on the tire bead on the other side of the tire to seal the outer sleeve at the lower part or the tire bead part on the side of the tire. The technical solution of the present invention can increase the number of times of using the sealing sleeve package, and solve the problems of high cost, short service life and inconvenient operation of existing rubber sealing sleeves. |
