Schwalbe Land Cruiser HS450 Tyre - 700 622

I recommend this product

These roll really well on tarmac and are not too bad on loose surfaces off road. Not as good as a full mtb tyre in wet muddy conditions but then you wouldn't expect it to be. I've not had many punctures and they seem pretty robust. For the money they are brilliant. I've got them on an mtb and also on a cyclocross bike. Downside is that the sidewalls are showing ageing quicker than I'd expect, although this appears to be quite common in tyres ive bought recently.
