Thanks, didn't realize this thread was getting stickied!

My main rides are no longer 27" tired (mostly ride my 26" '85 Cimarron these days) so I haven't kept on what's available as much, but I see there are lots of new suggestions in here. I'll work on snagging some photos and links and updating the original first post soon.

Edit: Fixed a lot of broken links, removed some tires that no longer seem to be available, and added a couple new ones mentioned in recent posts.
