Thanks. I put the contis back on the rear to replace the hutchinson fusion 2's I'd worn out and didn't get the same cornering I was used to. I barely missed wiping out on a down hill section and somehow managed to do a fixie style skid to straighten out. The sidewall tear was tiny so I put it back on. It feels like the tire itself had already flattened out after a handful of rides. Unfortunately, I did not buy this one from RC and it's been a while.
Like you say, it may have been a lemon, but I'll be switching back to Hutchy's. I'm not much of a speed demon, so I don't mind the extra weight/rolling resistance.
