  TYRE REMOVAL

1. Let the air out of the tyre by depressing the valve core (the little 
    pin in the centre of the valve stem opening).

2. Separate the tyre bead from the sides of the rim by pressing with
    your thumbs. Work your way around the tyre on both sides to be sure
    that the beads of the tyre are not sticking to the rim. (Figure A)

3. Stand he wheel up on the firm surface with the valve stem on the 
    bottom and grasp the upper part of the tyre with both hands. Try to roll
    the tyre off the far side of the rim.

4. With the wheel standing as in Figure B, use bicycle tyre tools for spoon 
   handles with rounded ends (at least two-preferably three) to lift the bead 
   on one side of the tyre off the rim. Be careful not to pinch the inner tube 
   between the tyre tools and the tyre bead or rim. Once you have got the 
   bead off for about one fourth of the circumference of the tyre using the 
   tools, the rest can usually be pulled off by hand.

5. With the bead on one side of the tyre completely off the rim, you can 
   now pull the inner tube out from between the tyre and rim everywhere 
   except in they are of the valve stem.

6. It should now be easy to pull the tyre the rest of the way off the rim. 
   Start at the side of the wheel opposite the valve stem and simply lift the 
   bead of the tyre up over the side of the rim and pull it off.
