You aren't going to "heat cycle" tires doing normal street riding, so don't expect them to get burning hot, particularly in colder weather. And normal street tires don't need to get burning hot to be effective, either.
While cold tires obviously have less traction than warm ones, remember that when it cools down the pavement also gets colder, and all of the contaminants, such as oil, antifreeze, tar, etc... on the roads become that much more slippery. You have to watch that in cold weather, particularly once it starts raining.
60 degrees isn't that cold though. I don't seem to have a problem in 50-60 degree weather once I've ridden a few miles.
