@SatNav:

Got in a wee bit of bother myself recently with a pair of Marathon winters.
Like you , I started with the intention of fitting the tyres, then going for a ride to try them.
Still never done that ride - need to wait for my next day off now, don't fancy having to them explode while on my commute.
Having previously fitted a Marathon original, I did not expect the battle I had with the Winters.
Like you, a ripped an inner tube with the lever, after an hour's fight.
So I went for a walk to buy some more tubes - fortunately in my local pound shop at the moment

I remembered the you tube video mentioned above, so I got some cable ties too.
Then I remembered a tip read on here a while back, so I got some talcum powder too.
The talcum worked a treat, got the tyres fitted with little bother after applying a liberal amount on the tubes.
Needed tyre levers only for the end bit.
Another great tip from Cycle Chat
