Drove summer tires in 17F weather tonight through 260miles

I've been rolling in winter rims/tires since I got the car last Tuesday. Been too scared to try summer tires on but the temperature during the daytime has been picking up and I didn't want to continue running down the thread on the winter tires. Drove to Foxwoods (130 miles, 2.5 hours one way) and back just tonight and it surprisingly wasn't too bad. The car doesn't feel as planted but I had no problem crusing 50-90mph. Mostly 70-75mph.
I was reading on a lot of near-miss accidents with the summer tires turning into "hockey pucks" below 25F. Perhaps my tires got a little warmed up after driving for a bit but I'm very hesitant to punch it. It only takes one time...
