Why do you lose steering with 2x Pink or softern compounds less than half way through a run? Someone explained it is because there isn't enough heat generated in the tires in the stock classes so the harder compounds change less than the softer ones. Is there another reason?
I would venture to say that the softer compounds would tend to be "stickier" and pick up more carpet fuzz/debris etc. As the tires heat and become sticker, they would tend to pick up this debris and lose traction in the middle of the run. The harder tires would provide enough grip but not be so soft they pick up a lot of the junk on the track.
