My rear tyre has a nail or similar in it (I can only see the head) which is a very slow leak. The nail is near the centreline and appears to have gone in straight. Usually with my car I'd just swap to the spare and take that wheel in to get fixed. With the bike: 1) Only having a single rear tyre, is anyone confident that a tyre can be plugged/fixed successfully or would they just buy a new tyre for safety's sake? 2) Do normal tyre shops do bike tyres or do I need to go to a specialist bike store? 3) Do I need to take the rear wheel off first or will they do that for me? Tyre is pretty new and only has something like 5000 k on it. It's a goodyear something which, apparently, is not a particularly good tyre.
