(both were broken when I went to use it on w/end)
When you look at them the rubber seems to have deteriorated and has
loads of cracks .. this makes the machine a real pain as new tyres are
~£13 each.

When not in use the blade tension is slackened off .. and you can't over
tension the tyres as tension set by wheel diameter.

Anybody else have this problem ?

Not had it with mine...

Could it be related to the environment in which the saw is kept?



You need to keep rubber lubricated and out of UV or this happens.

Castor oil is what we used to use on model plane 'rubber motors' or
glycerinene..there are custom made 'lubricants' that help.

e.g.

But I cant help thinking that the rubber should not be doing that inside
in a workshop.,

My guess is you are buying a naff brand of tyre.
