Hi i asked the same question a month or two back. I spent hours on the internet and came up with a recurring finding that they have a tendency to slide off road but are very good grip wise on tarmac but tend to generate more road noise. In the end I plumped for TKC80s ( see my thread tourance to KTC80) in the tenere xt66oz,- tyres section.
