>>1803739dont worry just take a metal file and grind down the rim edge that is a little sharp. If it makes a bothersome noise then take the same file and file down the rim brake track a bit but don't go crazy. I say use a traditional hand file if you have one but perhaps some better experienced anons can tell you whether to use a dremel or what. I only had to file a rim gouge once and I used a hand file.
Also consider it lesson learned that tanwalls simply do not provide the same protection as full rubberwall tires. It's not your fault. they are marketed to people who like tires and pros ride them- but they simply are not as good as the same tire fully walled.
