Dunlops are factory installed. They suck. My rear tire is shot, with less than 8000 km on it. It's at the wear bars already and will have to replace it before my next long trip. The front is still pretty good, maybe half way worn. I keep a close eye on tire pressure and I don't ride excessively fast nor do I ever carry a passenger, so the tire being shot at 8000 km is unaccpetable. Tourances will go on the rear first, then the front. I had Anakee's before on my previous GS and at 12000 km they were still good for another 2 or 3000 km.
