For off road my bike came with rocket rons which were fine but when I needed a rear replacement I fitted an MP mtb tyre which didn't give any confidence at all on anything other than a dry trail. Wouldn't have another for off road.I'd be interested in hearing which tyres you use for winter riding. I have Marathon plus ones installed but thinking about changing them for the winter. I wont cycle in icy weather but perhaps cold, wet, occasional snowy urban commutes.
