Where there might well be a problem is that they are narrow high pressure (200psi) tyres not ideal on soft ground.
that is exactly the problem - no ability to spread the weight on boggy, icy, sandy, shingly or pretty much any type of ground except a hard, compacted surface. Where you need the equivalent of a fat mountain-bike tyre, you have got the equivalent of a high-pressure racing road bike tyre. Even a double-bogey would have helped.
