I was getting frequent glass flats with Conti Super Sport tires, found that Hutchinson
Globetrotter 700*28's rode well and were much less flat-prone until the tread wore away.
Currently using Vredstein "Perfect" 700*32, which seemed bulletproof for the first 5000 km (until
the tread wore down) except for wet glass, which also cut through a Mr Tuffy before I got the
Vredsteins. Up to 7000 km, had a few flats, one from a piece of wire.
I believe they're available in larger sizes, but I really hate how they feel, and plan to try
Panaracer Pasela Tourguards next. Probably 700*32, although they're available in 35 and
possibly wider.

You might search www.deja.com for "mr tuffy" or "tire liners" in this group. Some people like
them. I found that they chewed through several tubes, and finally the tire casing, even after I
had tapered the overlapping ends as described in the newsgroup. And a chunk of glass went right
through on one rainy day (wet glass cuts very well). It was pouring, and I didn't realize they
were replacing the windows in an apartment building I rode past. When I say CHUNK of glass, I
mean CHUNK of glass. :-(
