New Hankooks but concerned
I just put a set of Hankook V12's on the Cayman. They are mounted on 18" OZ Allegeritta's. I have noticed they seem to be vague and find myself drifting in the lane driving down the highway. The rear seems to be slow to follow the front when turning. I have a general feeling of uneasiness when driving the car. The original tires were PS2's and I felt very confident with them, even with them being at end of life.
Today I was driving home on a 50mph road following a pickup truck with a load of furniture. A chair flew out and headed straight for my windshield. With just muscle reaction I sharply turned left then corrected sharply right with cruise still on. Cruise cut out as PSM had to take over because the rear started to over-correct. Growling was heard from the tires during the time.
It all worked out but I just left feeling uneasy still.
The car has not had an alignment yet since the new tires were put on.
I have never owned a car where I could feel differences in tires so I am looking for opinions on these sensations.

Alignment.
Check tire pressures.
Takes about 500 miles to wear (scrub) off the mold release.
Make sure they are mounted correctly- directional tread.
PS2's are great tires. Hard to beat. So, your new tires may pale in a direct comparison.

Thanks for the reply.
Pressures were about 40-42 in the rear at the time.
I check the rotation marks and they are correct.
I am below 500 miles at this point. I think I am around 250 - guessing.

Compared to the PS2's or RE050A's, the V12's are a little less sharp by comparison. They will get better though after break in and after the tread wears down a little. Despite the fact that it may soften them a bit, I'd recommend a little lower pressures; maybe 38ish hot.
