Surly Extraterrestrial 26x2.5 ... but they appear to have a bit more aggressive treading than the almotions, and of course are much wider at 2.5inches, but in my mind, if the almotion is kind of like a "light" version , tread wise , of the ET's, they probably would work well.
For sure, the mondials have deeper side treads, but its really hard to know without riding on a given surface to know how each tire would behave.
I suspect that I would prefer the easier rolling almotions, especially as I am pretty comfortable riding on all kinds of stuff on slicker tires, and lower pressures always help.
Agreed on the Almotion vs ET stuff. I pretty much decided if I were going to ride a significant amount on pavement, the Almotions would be great, and would handle the off-pavement sections as well. When I did my rail-trail/canal trail trip, it was largely off pavement, and I would have taken the ETs if I had been able. But the Almotions did fine. I haven't really considered the Mondials only because they aren't made to run tubeless, I don't think, and the tread on the Almotions seemed like a good match for the Big Bens they were replacing. If I were looking for a tubed, all terrain tire, I think I'd lean more towards the Mondial, but hopefully someone who has ridden one can chime in.
