Tire replacement after Roadside Jack Woes


In another post I mentioned that as part of my nightmarish intro to using the MB jack, I had to replace both rear tires. All that were available in Tucson on the weekend were Pirelli P Zero Nero. At $401 out the door the price was right, but I'm very, very concerned about performance.
On my usual route to the airport this morning, I took a couple of curves at a speed that with the old Michelins would do nothing to make me concerned. Well it was quite different today. I thought I was going to lose control and the dashboard warning was going nuts until I got straightened around.
Is it possible these tires could be this bad (different), or should I be looking for another cause. FYI, I re-checked torque and set to 96 ft. lbs. per manual.
Thanks again for all you help!
