Actually inflated on 819 without sealant and held air well. Bit of bonty juice and stayed up fine. Mud X on the other hand, needs latex as the super juice doesn't hold pressure.
Loads of grip and worked really well at low pressures, particularly in forest of dean, but xc in Cotswold clay wasn't such a good idea (no clearance).
I don't know whether it will inflate BUT… having used both sets of tyres I would recommend taking it back because the 2.35 TR WET is a fantastic tyre and IMO rolled a lot better than the 2.5 and gripped just as well. It's pretty big for a 2.35.
I used my 2.35 TR until it looked like this and it was fantastic in everything except for really claggy mud:
