So far that's always occurred indoors shortly after installing the tire. Switching the rear wheel resolved that issue. Now I need to replace the front. Or switch to tighter fitting tires, such as the notoriously tight Continental Ultra Sport II.

One of my latex tubes seemed to have a thin spot, the equivalent to an aneurysm, when partially test inflating it to check for punctures. It would probably hold within the confines of a tire. But I retired that tube after two punctures anyway, since the second hole was at the base of the valve stem and difficult to patch properly. I'll cut it up to use as patches for other latex tubes.

We don't have any mountains here, and no downhills steep enough to require more than occasionally touching the brakes if it's a group ride and others are slowing. No risk of overheating.
