Well it looks like I've worn out the 1.5" Pasela TG's on my RST after about 5000km - I think the commute across heathy forest tracks has brought them to an early end, with the sidewall tearing away nicely. With my previous bike I just used to keep going with Conti Top tours.
I would like people's thoughts on the relative merits of:
Conti Top Contact (50-559) - has anyone used these - are they worth that much? are they not a bit heavy?
Conti Travel Contact (47-559)
Schwalbe Marathon Supreme (42-559)
Pasela TG's - should I go for the 1.75" this time? - I'm not sure these will give me much more grip.
As far as I have gathered, the key issues are - rolling resistance (and thus speed / effort);
About 80% of my commute and regular riding is on country roads, the rest is on on forest tracks, sections of which are soft sand, and one section of clay. So although I want speed most of the time, I do need to have something to pull me through rougher ground.
