This is all due to temperature. Note in your owner's manual how it does not suggest driving the vehicle when the temperature is 40 degrees or colder. Low profile and relatively stiff sidewalls literally give the car the feeling the tires are flat while turning when it is chilly. No issue when the temp is warm, but like many DOT competition tires, they are not advisable to drive without caution if it is cold outside. Will take quite awhile for the tires to warm, also , when the temperatures are down.
