I have experienced this same phenomenon with a set of nokian hakkapalitta(sp?) studded tires recently. Those things NEVER flat. After the second slow flat in a row, I figured it must be something wedged in the casing. It was NOT easy to find, but it was a small sliver of rusted metal about 3mm long- tiny! I still don't know what the heck it came from, or how it got wedged so deep into the tire. I guess it could have been from a chunk of rusted snowplow blade or something.
