and just now into the 40Fs the pavement may still be cold enough that the tire doesn't get warm enough for the "rubber" in the compound to deform and fit into the micro-irregularities in the pavement which is what gives you traction in a summer tire.

Wait till a day when it has been only in the 50Fs at night before making a judgment.

And be extremely careful any time the pavement has been colder than about 45 with summer tires...cost me a '99 when I applied the brakes and just slid in the morning when the temperature was probably 40 degrees but it had been colder the night before.
