new rear rubber and something is all wrong!!!

…had to change out my rear tires due to wear and a roofing nail, so i did, only not with a mating pair of potenzas, but with a pair of nittos…same rating, same dimensions so as to not disturb my ride height or anything like that…i went with the nittos because they were in stock…i didn't want to wait…so the 86 930 was butts up in the air for a day, i put the new tires on, dropped it, went for a drive, taking it easy…
…its been about 250 miles, and at higher than posted speeds on familiar, windy roads, the car is freakishly squirrelly…it feels as if the front end is sliding away from me, the steering wheel is "over" responsive…and its scary!!!
…any ideas would be appreciated…

I've had this happen to me on my 996tt when I put hankooks on the rear with continentals on the front. I believe it was due to the much softer sidewall of the new tire. Once I put matching tires on the front it felt better. Which Nittos did you get?

Yeah those arent great. Sometimes the tire shop will let you exchange them. Tell them the situation and that you feel the car is dangerous the way it is and see what they say.

I worked in a tire shop when i was a kid in high scoool. I was told not to mix brands of tires front to back because they had different slip angles. So they would not perform the same.

…thanks guys, i think i will try to exchange them in, and just wait for the potenzas…it was naive of me to think there wouldn't be a noticeable change in drivability…my "why should there be?" has all too quickly turned into a good stiff kick in the head…must be world cup fever!!!
