If you have to remove a very old and hard tyre.
You will often find that you can get one bite over the rim, with a lot of effort, but it will refuse anything else.
With the one "bite" hanging over the rim, then take a hacksaw and cut it CAREFULLY through (across that edge and half way to the middle). It only needs that one cut, the metal strands will part and relieve all pressure; the tyre will now peel off the rim by hand.
You MUST have some of the tyre, over the rim, for this to work. Otherwise you cannot get to an edge as it's in the rim.
I'm with Silas.
I just use the airhose to slightly inflate (opinions vary on this bit) and fit the tube and tyre.
I then inflate and bounce it about to get it popped up onto the bead. Might take a few goes.
Note that many tyres have a line along each edge that gives you a clue as to whether it's evenly seated right up to the rim.
Are we finished here, you think ?
If so, then if Brenton sends me his images then I'll pdf and create a home on our website for these things.
Must get around to doing the rest of the bulletins,as well (that is DULL)
I have a WNG to go together this winter and a 500 to convert to twinport.
I can do pictures on those.
