Conti Vert Pros (but they are about to be replaced with some Conti Mountain Kings (Black Chilli) - so hopefully they will be just as good.
I tried a 2.2 Nobby Nic 2 nights ago and was mighty impressed with it, so that would also be a consideration for me.
I got High Rollers (folding 2.1's I think) on the Marin when I bought it and they were very sketchy - lasted 3 rides - great in the dry but the slightest bit of mud and I couldn't keep a line and cornering was very worrying (saying that I'm not claiming to be a great rider).
So personally, I've had real bad experiences with the High Rollers (admittedly only about 30 miles on them but enough to scare myself silly); Conti Vert Pros are very long in the tooth now but they seem to work well in all conditions, I'm hoping the Mountain Kings will be just as good (they look very similar) - I'm getting them at a silly low price so if they are junk, I won't be shy in saying so - seem to have mixed feelings to them on here but other review sites seem to suggest they are fine.
I'm just looking for a tyre that doesn't spin out when riding over any ground (apart from thick snow, ice and wet roots - I'm expecting all tyres to spin on those) - keep me going in mud until I physically can't go on; clear well once away from the mud and offer grip whilst cornering. I'm not overly bothered about tyre weight (although I'd steer clear of real heavy stuff as my legs would suffer!), so as long as the tyre ticks those boxes then I'll be happy with it...the idea of changing tyres for each ride seems a bit strange to me - I know loads of folk who do it, but it just seems a waste of 20 minutes on a weekly/daily basis to me.
If I had the cash to spare I think I'd be looking at some Nobby Nic's, but I tend to react badly to having to pay more than 20 quid for a tyre - not really sure why as a good tyre can make a huge difference to a ride.
