This is probably a pretty basic question, but it's odd to me. This morning, my front tire was flat. When I changed it, the rim tape was out of place and that's what had caused the flat. This tire / tube has never been off the bike since I got it over 4000 miles ago. Could it have taken this long to flat? Or could something have caused it to shift?
I repositioned the rim tape and put the new tube on. The old one had 3 holes and slime in it (slime no more, took 10 minutes to clean everything up). Should I replace the rim tape? It looks like a rubber of some sort. I had to be careful for it not to shift over the nipples when I was putting the new tube back on.
