I only got into MTB'ing this summer, and tyres have been my biggest headache. All my off roading has to be preceeded by a road ride as well as getting back home too. (I dont drive) Therefore, I need a tyre that offers good off road traction, without giving horrid drag on tarmac. I began with a pair of FAST FRED from the Schwalbe stable. Great on road, naff off road unless on dry hardpaced surface, slightest bit of damp and i may as well have been on slicks. So I quickly switched to a pair of KENDA SMALLBLOCK 8 (2.1") These were terrific off road in dry and damp conditions, but even at high pressure, were hard work on tarmac. I would get them up to @ 60psi before leaving home, that wasnt too bad, but on going off road, I would drop the pressure to between 25 and 35 psi. That would give me all the traction I needed on hardpac, woodland, bridlepath and off piste. But the journey home on road would be very tiring at these lower pressures. Just as autum began in earnest, and I started to find the KENDA was not so good in full wet and mud, I took advice from a fellow biker, who urged me to try a combination of a RITCHEY SHIELD (2.0) for the rear and a GEAX SUGUARO (2.2) at the front. This I did. I've only had them on for a fortnight, but have been VERY impressed so far. Having them both at @ 35psi gives very good rolling quality on road, and superb traction in full mud, as well as on hardpac, woodland, bridleway and anywhere else I have managed to get to, in dry, wet and damp conditions. So far, this combination has been exceptional, and for my own circumstances and needs, have no hesitation in recomending that you give it a try.
