Tyre for varied terrain: cyclocross v wide file pattern

So this is the question. I am training for a long-distance event that is mainly hard-packed dirt or gravel roads, some stretches of tarmac and some stretches of loose dirt (mud if it rains, although it will be on early summer, so little chances of that). I did that terrain some time ago on full knobby tyres, and it was overkill for 95% of the terrain. Right now I'm setting up a bike from an old rigid mountain bike, I've set up a touring handlebar (although I may change it for a Jones Loop or similar if I get enough cash, because I find myself on the "curves" 90% of the time wishing I had the brakes there). I put some "grooved slicks" on it (basic vittoria randonneur), which are great for road and extremely hard-packed dust, but the tiniest bit of sand or mud makes cornering a slippery business, so I'm thinking of what to do, and considering two options which I think they could work, although they are very different.

1) Cyclocross-style tyres (Think Schwalbe CX PRO 26"x1.35). Narrow with low-profile knobs, but definitely knobby.
2) MTB "Slick" (I'm thinking of the Schwalbe Sammy Slick or CX Comp): This is, a wide tyre (26x2.1 the SS and 26x2 the CXComp) with low profile knobs on the corners and a "file pattern" more than knobby centre.

Speed is a relative concern. I'm working towards riding a bit faster, but I'm not racing. The event I'm training for follows a river so it has wicked descents on tarmac, long flat sections on dirt, gravel or tarmac, a climb on dirt, a climb on tarmac and a leg breaker of continuous ups and downs on semi-loose packed dirt. No singletracking and no ascents any steeper than, say 20%.

Unlike your thread title, none of the tires you mentioned are actually slicks. You did comment on the fact that the fastest ones have file tread, which work great on hardpack and dirt roads which don't have mud or sand.

So they will all do much better than a road tire. I ride my CX bike in the conditions you describe and I'm currently using a 700x32 Vittoria XG Pro. Next go around, I'll probably go wider up into a file tread tire in the 40mm range.

There's a big range of cost in the tires you talked about. The CX comp is an old design, heavy, and doesn't roll as well as other options but it would work and it's anywhere from 1/2 to 1/4 the cost of alternatives. You will be limited in tire selection since a lot of folks will be using 29er or 700c cyclocross tires for this type of riding. A narrow 26" tire is a pretty small diameter.

Messed up the title, true... But then, between a narrow knobbier tyre and a wider file tread, what would you choose? Budget is limited, but not rock bottom: no more than 50/60 euros for a pair.

Definitely file tread. I forgot to mention something important about my Vittoria XG Pro tires: they were a gift.

If I had paid for them, I'd be riding something else. The tread they have is not that useful, and they actually don't roll as fast as file tread. I think file tread with sparse, low shoulder knobs are the way to go.

For your experiment I'd keep it cheap; try the Schwalbe CX Comp.

I'm rocking Panaracer UrbanMax on my CX/commuter bike(700x35). They work for most everything except mud. I run them at 80/85psi on pavement and swear they roll as good as my expensive 25c tires on my dedicated road bike. When traction starts to become an issue in softer soils I'll drop the pressure down 10-15psi for those sections if it is long enough to warrant the effort. Then I'll pump them back up. I did a muddy, sloppy mess of an event a few years back on smooth Conti Gatorskins (700x28c). That was scary on the descents and too much hike-a-bike on the climbs. It was my first event of that type and I only had one bike and one set of tires.

Check out the Conti Crossrides. Overlapping center knobs so the rolling resistance on pavement isn't perceptibly different than skinny racing slicks and a nice aggressive knob pattern for when it gets steep and loose. Relatively inexpensive and supple comfortable ride too. I have only ridden them in very short muddy stretches, (hey, its Cali and the great drought) but they seemed to clear the mud out well and not throw it all over me. Never seen them in anything other than 42mm so make sure they will fit.
