Buffing tool (10, 10a) and method for preparing internal surface portions (14) of a tire (13) for application of a sealing patch thereto. A puncture (12) formed in a beadless tire (13), having a tread formed integrally therewith, is difficult to prepare for patching by use of conventional buffing tools and methods due to the mass of tightly wrapped reinforcing wires and multiple plies incorporated in the tire. The pencil-like buffing tool (10, 10a) embodying this invention comprises a shaft (15, 15a), a buffing tip (17, 17a), and a hinge connection (18, 18a) for pivotally mounting the buffing tip (17, 17a) on the shaft (15, 15a) for movement between a first, installed position aligning it with the shaft (15, 15a) and a second, operative position, for buffing the internal surface portions of the tire, responsive to rotation of the buffing tool (10, 10a). |
