I've now got Schwalbe Marathon Plus (http://www.schwalbe.com/index.pl?modus=lang&punkt=7&abstract=1201&bereich=&einsatzbereich=&produktgruppe=) tyres, (a href="http://www.wiggle.co.uk/?ProductID=5360007837">these)but I suspect that in the rain even they would be vulnerable to glass. Drakes had a section of one with drawing pins to try pressing onto it.
And I haven't had a puncture on my rear tyre since I got an Armadillo outer tube last year (but again, don't know how it would stand up against a centimetre of glass...).
Wet glass will cut anything - Kevlar or no (and Kevlar's weave is useless against thin penetrators) - but I suspect these work primarily by being thicker than most penetrators.
It'll work, but I think the rolling resistance must be quite high.
From the way other people are reacting, I assume it's a bike tyre, not a car tyre?
If so, I'm surprised at the suggestions to pay extra for more resilient tyres. I'd have thought it was cheapest and simplest to pop on a spare and repair the damaged inner tube to become a new spare.
A bad night out biking (mountain biking for me) can mean 3 punctures in fewer hours. It doesn't take many chilly evenings ripping the dead inner out of the tyre and replacing it with a new one for the value of more resilient tyres to be increased!
We run tubeless now. So far so good, but the day I get a puncture in one of these is going to mean more pain swapping the valves on a chilly evening, probably in the rain!
Sure. But sooner or later you need new tyres, and changing flat tyres in the rain is tedious so it's worth at least considering paying extra to avoid it. (I used to commute on a route where I was getting several punctures a month. Eventually I gave up and got closed cell foam tyres (http://www.greentyre.com/eng/index2.php). They weren't very nice tyres, but they didn't puncture. I went back to pneumatic tyres after breaking a rim on a pothole, by which time I'd changed jobs and commuting route. (Given my weight, I probably should have been using wider tyres all along and the rim might not have broken if I had, but the pneumatic ones do have a better ride, lower rolling resistance, and better grip going over painted lines on the road (I never actually fell off with the GreenTyres, but they always felt a bit dodgy going over wide fresh lines). It's possible that they've improved in the years since though.)
