|Schwalbe Marathon Plus in 25 mm.|
A few notes:
1. Hard to mount, although they are the first wire-bead tires I've mounted in -- literally -- years if not a decade, so maybe this is par for the course and I had forgotten. I had to fight to seat both beads in one place, wrap that with a Velcro strap, and move around the wheel adding straps until enough was seated that the beads would not pop out unexpectedly.
2. They look awesome.
3. They do next to nothing on packed, grooved, ice.
4. There is something just a tad off about 25 mm. semi-all-terrain tires. 28s are a tight squeeze on this bike in the best of circumstances and I was concerned that 28s with tread would not fit.
