Managed to get some trail use on these and I can say at 28psi they are not a mud or slimy conditions tyre. Had some buttock clenching front end pushes and some back end slides when moderate with the throttle trying to get out of even slight ruts. Dont now how much better they'd be aired down. For slow plodding they are obviously better than siracs but soft wet mud has the front tested quite early, one patch i hit required a dab to save a front end washout ... That said the suspension soon shows its limits early if trying to press on on stock soft settings, bottoming out forks and shock without much provocation, so that seems to match the tyres limits in the wet mud .

On road they have more grip than seems wise, but its not been much better than damp or around 5~0 deg c so I havent spanked them but no slides or puckering ringer during my road use up to NSL or thereabouts.
Good road occassional trail use (easy) but if planning on a rally then maybe best saved for dryer conditions.
PS my offroad bike skills arent owt beyond rank amatuer if that but used to be handy on my mtb (before fat middle age took hold).
