Jonathon- In my experience, the glue will dry out somewhat over the winter. A good rule of thumb is to re-glue at least once a year. The old dry glue will still adhere fine, but it will be harder to change in the event of a flat. Possibly more importantly in the case of a flat, you want the glue to be somewhat tacky so that the spare sticks to the rim.

You don't need to clean the old glue off the rim every time you install a new tire. You should be able to get 3-4 reglues or new tire mounts before having to strip the old glue off. Stick with the same glue every time though.

Sweet,

Follow up questions if I may. First, you are supposed to apply a layer of glue to your spare, right? Second, if you are to pre-glue the spare, should you scrape off the glue at some point if it hasn't been used and re-glue it? Thanks in advance.

Yes, you need to put glue on your spare. Don't worry about scraping. The glue really doesn't build up that fast and you would have a hell of a time trying to scrape it off. If I get lazy and haven't re-glued the whole wheelset in quite awhile then I just make sure the glue on the spare is fresh.
