tyres

I ride one of those hybrid bikes that is for road and cycle tracks. The
tyres that came with the bike are CAMEL 700x42C. They are smoothish in
the centre and more 'grippy' on the outside.

"Grippy", if you mean knobbly, is only actually any use on soft and
loose surfaces. On hard surfaces like tarmac they are actually /less/
grippy and also more work.

The thing is that on the cycle tracks and waggonways there is broken
glass and already I have picked up four punctures due to glass in the
rear tyre, nil punctures in front.

Q. Are there tyres that are better suited to the cycle track
environment?

Yes. Narrower, for a start IMHO. There really isn't any need for
anything more than a 38mm unless you're dealing with serious mud, and
you could go down to 35 without any real issues. You can also get tyres
with an anti-puncture kevlar protection belt. Schwalbe Marathon Plus
(amongst others) should answer your needs, I think.

I run Schwalbe Marathons, which are fine on hard dirt/gravel and tarmac
and in the last few years (touch wood) have had the grand total of 0
punctures. Going up a muddy trail in the woods t'other week I was
losing traction, but that just added to the fun 8-).

Second that recommendation for the Schwalbe Marathons.

What's the difference between the standard Marathons and the "Plus"?

The "Plus" has, inside the tyre and towards the outer circumference (ie,
on the inner face of the rolling surface, but not on the inner face of
the sidewalls), a band of foam that provides a sandwich filling between
tyre and inner tube. The idea is that any short puncturing object
penetrating the rubber that isn't long enough to reach through the foam
won't puncture the innertube. It adds a small amount of weight. I
don't use it, so I can't comment on its rolling resistance compared to a
standard Marathon.

I didn't realise it was foam. That will keep the weight penalty lower
than it would be with normal tyre rubber, and maybe helps minimise the
amount of additional rolling resistance as well.

Specialized Nimbus EX is another tyre to consider. Takes something
unusually nasty to puncture it.

Marathon PLUS...............bullet proof!!

I've managed 2 in about 5 years with standard Marathons, in each case
very long very sharp needle slivers of glass. Very good tyres, I've
been very happy with them and haven't felt the need to move to the Plus.
Maybe if I lived in an area of industrial scale hawthorn hedge
trimming I'd think about it, but the kevlar bead on the standard tyre
keeps /most/ of the trouble out.
