Any review of the tires really depends on what use you intend for them, doesn't it? Here in the states I'd wager that MT's see more use on rock trails than in mud, so it depends who you ask.
From my own experience if you plan on a lot of asphalt driving as well (such as with a lot of dual use trucks here in the states) there are better tires than the KM2. The KM2 has a decent mud tread but is loud on the road and doesn't perform well in the wet. I don't know what types of terrain you are planning but the Interco TrXus MT line is very popular here in the USA, as they actually have a slightly more aggressive tread (better in mud) but are quieter on the road, last long, are good in the wet and mud, and also stick like glue on rocks. The KM2's where really designed for the rock crawling crowd and may be too specialized for what you need? Anyway, depends on what vehicle you intend to put them on and where you are going to go, but there are a lot of reviews on the web.
A popular sport here in the Eastern seaboard of the US is "rock crawling" so tire sidewall strength is a big concern. Earlier BFG tires didn't do to well in this area but the KM2's are supposedly much better. It all depends.
