I recently put on a set of Anakee tires on my DR650. I went with one size wider on the rear to 130. In three weeks, I had two flats with road driving only. I took the rim/tire in to the dealer to get a new inner tube put in and asked that they save to old one to see what was going on with these flats. I picked up the rim/tire and the old inner tube and found out that they had put in a 3.25-3.50 inner tube the time before. I also notice very fine hair line rips in the inner tube. I suggested that they had put in the wrong tube and that it was over stretching due to the tire width and causing inner tube failures and asked for a refund for the previous service charge. The dealer disagreed with me and stated that they do this all the time and would not give me a credit. This just can't be right!!! I do know this time that the dealer installed a tube for a 5.10 tire width this time. My next purchase will be tire irons and a lesson on tire changes.
