I'm not an expert but it sounds like the condition of the road (new and greasy) may have contributed a little more to this incident than the tempreture of the tire...again I'm not an expert.
I went riding into Sturgeon Bay Wisconsin from Chicago over the weekend at it was about 45F when i left.
THe words "Cold Tire" and "Grip" were flashing in my mind for the first 30 min of the ride.
Thankfully there were no issues...I'm on Super Corsa SPs as well.
Nonetheless, its good to know that you have no physical injuries from this unfortunate event and the plus is that fixes needed for you bike look minimal.
I'm believe fully that information is power and so many would have gained by reading about your experience....I know I have.
Thanks
