I carried all the way across Europe tyre levers, a puncture repair kit and two spare tubes for my Metzeler Tourances, then on my funduro. Luckily not a single puncture so didn't need them. I was then told by my motorcycle mechanic, I was wasting my time as there was no way I could get that tyre of the rim. Is this true? What options are there for repairing punctures, and how easy is it to do?
