I've got Tourances on the Tenere, and I'd say they are pretty much the same as the Siracs on anything but firm-ish ground. Great on fire roads, gravel, rocks etc but the front washes out at the first sign of grass, mud or sand (apart from deep sand for some reason!). That doesn't mean they behave the same on an R, I can't comment on that.

I've just ordered a pair of TCK80's for the Tenere, as the Metz is down to 2mm on the back and 3 on the front, and will be verging on legal after this weekend!

The Tourance are a good tyre, and great for touring with some off-road ability - on road they are hard to fault.

I'm not sure about the Bridgestones, I had deathwings on my Varadero and they were tourture in the wet - I've never gone back to them since (other than the XJR where the road tyres seam OK)
