If it's blue tyres you need, you can get Vittoria Rubinos in blue, only £7.95 from Ribble. They're a bit basic, but one I've been using for at least two winters just died on our club run today, and I'm just about to order more. Great value and fine for a winter bike.
What are they like for you know whats?
I've had at least 7,000 miles, mostly wet or winter ones, out of these and, until today I honestly can't remember having any, er, ahem, y'knows.
The one that died today had simply died of old age rather than any catastrophic failure; it was just worn through the centre tread to the canvas.
But it's quite flinty down your way, innit? I don't know how they would stand up to that: mine have a few cuts in them, but that doesn't seem to have caused any problems.
Like I said, they are basic, rigid tyres. I've used the 700x25s. They're not the fastest tyres in the world, but for the price I've been more than happy with them for what I use them for.
