Thanks.. may even put my original tyres back on which came with the bike (can't remember what they are). I went for the big ben to soak up a bit of judder. I assume the chunkier tyres such as the land cruisers are better for mud, but worse on road?
The Land Cruisers have a central ridge which should be OK on road - all depends upon how muddy the canal gets, especially if it deteriorates, as it does in winter.
I'm on a canal commute, using an old rigid MTB, but I can just squeeze guards in there if I use 2.0 tyres. I'm using BTwin MTB tyres, they have tread, but it's not too knobly, but they cope with mud, and roll OK on the road.
I've used the sides of a pop bottle and duct tape, to fashion a longer mud flap - this keeps the spray down on my feet and legs - just ensures I arrive 'cleaner'.
