On my bikes I use Schwalbe Marathon tyres mainly. I used a set of 1.75" Marathon Plus for a number of years while touring and on tracks similar to above, and really appreciated them as an all round tyre. The larger volume (previously on 1.5") gave a slightly softer ride, and the grip seemed to improve after a few uses. They have some tread, and with the wider footprint seemed to cope with off road quite well. The downsides are weight and a sluggish feel compared to lightweight slicks, but on the other hand I hate repairing punctures by the side of the road (and I never had to).

There always seems to be a deal on for these tyres on one of the online retailers.
