reet....
lay wheel on side. using a TL55 bead chisel and a lump hammer, break the bead on both sides.
when you done that take two big tyre levers and demount tyre from rim, removing the outer bead first (the one that faces out when wheel's on car).
once removed mark where puncture is then lightly buff area around hole, not too much cus you'll expose cords.
next, using a #6 reamer, drill through both sides of tyre but make sure last one is from outside.
then, apply vulcanising solution to buffed area, now get a #6 plug patch and place through hole and pull PART WAY THROUGH, leave for a few mins for adheasive to cure then gently pull so patch seats evenly.
then using a stitching wheel press patch down starting from middle to outer edge.
remount tyre, inflate to required pressure and check repair with soapy water.
if all is ok then remove exposed plug from tread of tyre, level with tread profile, ballance wheel and re-fit, remembering to torque & re-torque wheel nuts.
simple eh??
