Cold tires?
Mid-morning 75 degrees and sunny, I drove about two miles at highway speeds and took a slightly downhill freeway ramp (good blacktop)rather agressively. The tires began crying lightly. I could feel both the front and back get a little squirmy. I think active handeling may have been intervening a little as I let off the gas slightly. I didn't think I was into the corner that hard so I'm wondering if the tires weren't up to temperature yet.
It is an '04. I've only got about 2,500 miles on it and am still learning. I appreciate your thoughts.

Sure.. Tires need to warm up before you start getting agressive with them. Cool ambient temps have something to do with it, but you still need to get heat in your tires before pushing them even if it's warm out.
What kind of pressures are you running?

I'm running 30lbs in cold tires at 75 degrees.
Someone once said that John Heinricy suggests putting in 32 psi in the front and 29 psi in the rear (cold readings) for track use with the GY F1SC tires. For street use, 30-32 lbs cold should be fine.
I just think that you got a little too agressive with the tires before they got heat in them.
Edit: I see that you're in Minnesota. If you haven't been through a winter yet with the car, you will realize very quickly that the F1SC tires lose considerable traction once the temps dip below 50 degrees or so.

X - Pressures were checked after sitting in the garage all day. I'm going to check my guage against another but it sounds like I'm close to where I should be on pressure.
AU N EGL - Good point. I had put myself in a position where I was going down hill slighlty and catching up to traffic = no option but to lift a little. That combined with cool tires was all Active Handeling needed to see I could use a little help!
These cars are awesome performers but the laws of physics still rule.
Thanks for the input and enjoy the warm weather!
