Tubed or tubeless?
There're loads tho, depending on budget and bias (urban, towpath, light trails, road, wet, dry, heavy tyre, lighter tyre, puncture-guard level, etc)
For the type of riding you describe (road/towpath) you need something with low rolling-resistance but with enough grip to save a washout on muddy towpath puddles? The latter can be solved simply by slowing down through the slidy bits, leaving you free to use more slickery-fast treads than more aggressively-treaded hybrid-types.
Maybe take a look at the Schwalbe lineup for this type of riding? I've used Hurricane, Marathon Racer, Silento and Land Cruiser all on a 26er. Favourites were Marathon Racer (back roads) and Hurricane (50/50 on/off-road)
- Schwalbe Marathon greenguard (Marathon Plus are heavier, more money, yet max puncture protection)
- Schwalbe Silento - (currently have these in 35c flavour on my towpath plugger)
- Schwalbe Land Cruisers - Similar to Silento but more offroady. (Check Wiggle sale think theyre £8 atm)
- Schwalbe Big Apple (love these slicks in the summer, and offroad even, esp the 2.35s)
- Hurricane 2.0 (not so quick on road as most of the others but great profile for 50/50 road/trail)
Go as wide as you can, better comfort and rolling.
