Not sure how the 2.25 will help in really deep gloop TBH, as there a not a full on mud tyres (ala Trail raker or Swamp thing), more of a compromise all rounder with mud ability, and the extra width ain’t gunna help for that.
That said I believe (after 2 rides) that there very good, I feel more confident since swapping the Ardent up front & believe there holding lines better in the mud, but I’m still riding with the mindset of where the Ardent could be pushed to, so am yet to explore the limits of the tyre.
Also this is my first 29er “mud tyre” and only 2nd front I’ve used, so I’m hardly in a position to be able to exclaim that there the best winter tyre out there…
