I am fairly new to bikes and have come across my first nail. Tire is still inflated, but what do I do about it? With my cars I usually just stick one of those tire repair kits you get from the local auto parts store, I assume I should not do the same here. Does the tire need replacement, or is there a patch available (even if only dealer available)? The dealer I bought the bike freom said that tire is brand new, so replacing it would be a waste (and paper flying out of my pocket always sucks). Suggestions? It is the rear tire on my X.
