I have a 16-month old 1200GS, which I have owned for under 3-months. It had 7,000 miles on it when I bought it and I have put almost 2,000 more miles in. It has Trail Wings on at the moment and the rear is heavily squared (it was when I got it - honest) and is now down to a couple of mm in the centre, the front looks something over half-worn. I am pretty sure these must have been the OE fitment. I am a reasonably 'enthusiastic' road rider and have noticed that the rear is now graining significantly at the edges of the blocks. It also skips and slides a bit when driving hard out of corners - roundabouts mainly - but this may be in part due to the squaring and resultant reduced contact patch when coming back upright. Not sure about the wet grip - seems OK-ish but not great.
What I want is the best wet and dry grip (in that order), regardless of wear-rate, dual-sport tyre (I also intend to do some gentle off-roading too - might as well now I've bought the bike!).
The BIKE test has raised more questions than answers - no wet test - why?
Torn between Trailmax (look more roady) and Distanzia (look blockier). Had Tourances on an F650 a few years ago - they were OK but if they last that long doesn't that point to them generating less friction (grip)?
Any suggestions - other than two sets of wheels?
