Managed to mount both sets of Muddy Mary's up, tubeless, the FR onto ZTR Flows and DH onto Mavic EX823s.
Previously had Specialized Chunder SX on the Flows and Maxxis USTs on the 823s, both of which required very little effort to mount, popped both tyres on with the bead in the central channel, pumped up with a floor pump and away they went.
The Schwalbes needed a little more effort though, had to inflate the tyres with a tube to set the bead, remove the tube keeping one side of the tyre still seated to the rim, pour the sealant in, install the vale, carefully persuade the unseated side of the tyre back on, then they inflated fine. Bit of a PITA doing four, what I thought was going to be a 10 minute job eventually took a lot longer!
Schwalbe's 2.35 is the equivalent to Maxxis 2.5 and I suspect the Vertstar compound is softer than Maxxis' 42a, you can feel the rubber stick to your fingers when you touch them. Just shoving the bikes around with the new tyres on and I can feel the drag from the new rubber, whether it's a the tread pattern or the softer rubber I can't yet say. Hoping they don't take too much speed off my riding though.
