In case your going to different size tires..here is a link to the tire rack chart to help you .http://www.tirerack.com/tires/tires....re=44YR8K110XL
Again..I do not know the tolerance level for different heights of tires in various sizes for the corvettes active handling system. That you will have to check with other knowledgable people on this site.

If all that changed was the tires then hmmmm, I suspect the tires.
Just cause the tires are same model/size as before does not mean they are the same construction. Manufacturers of all products make running changes, some will note it, others just make changes and say nothing.

It seems as if they are getting better. I ran about 300 miles today mostly in the rain and I am now of the belief that it may have been a preservative on the tire. Today when I got to some dry pavement i made some hard turns and it held much better without activating the active handling. I have never had a set of tires do this, its not very safe. Thanks for all the help

34 psi is a little on the high side. I would keep it at the factory recommendation of 30 or maybe a little lower. Make sure the rear tire pressure is no more than the front and if looking for better handling make it a couple pounds less than the front.

My AO 2008 coupe felt downright spooky on the way home from the tire shop after the new Hancooks... It has taken thousands of miles now and it is getting better, but still nowhere near what it was when new. I also rotated the fronts (several thousand miles on them and cone shaped) at the same time so that is a possible reason too. Now that the front's are worn down to "even", I'm going in for the alignment to pull most of that tire killing camber out. Mine is a freeway flier, so straight line stability is king.

I put the hankook 265/35/18 on the fronts and the problem is completely gone now. It was deffinitely the preservative. just turned 111K after trip to birmingham. I am now trying to see how many miles I can put on the car in my lifetime. I am of the belief that there is no other forum that will give as much detail as this gang does. I will be a vette owner for life.
P.S. I am pretty sure its not the color.

New tires tend to have a film on them from time to time ..
I think it keeps the tires fresh?
Anyways....after checking to make sure all the bolts are tight on the wheels..
I would say driving a few hundred miles and the car will drive fine ..at least I remember it did for me a few times after a few hundred miles with new tires on the car..

same thing
i have a 2000 and just put new tires on the back. I have KDW's on the front wearing evenly and the backs were KDW worn even as well. I put Dunlop SP 9000 on the back in the correct size for the rear. Same issues. Handles as if the rear is slipping. It is now work to drive on the highway, it follows everything. I tried more tire pressure and no change. I hope it is the release agent but i have over 300 miles so far....
I am going to set the pressure in the rear back to stock and going to do a couple of long burn outs and see if it gets better.
Great forum, at least i know i am not crazy about the weird handling.
