I've got about a 1000 miles on Pirelli cinturato p7 all season plus. 245/45R20 99V.
Terrible tire as for handling. They do not want to roll as straight as the Michelins and result in more sideways movement on less than perfect road. They do steer a little easier. I feel a lack of confidence in this tire and that is without driving on anything wet, snowy, or having to do panic stop.
My vehicle, 2010 MKS 3.7L
The OE were Michelin Primacy MXM4. I was happy with them but I developed a handling problem around 28K miles. Turned out the tires had worn in a bad way. 9/32 at shoulders but 7/32 center rib. It was not an alignment and tires checked monthly to within 1/2 pound to factory pressure. Michelin said "it just happens sometimes." Hesitant to use the same I moved up to Michelin Pilot AS3 but Ford dealer made a mistake in that they put 103Y on instead of 99V. I was very pleased with the first half wear. It was getting a little hearse beyond that. And Michelin had a really great warranty back then. Covered fully to 4/32 wear. And at that point I got four nails in one. It went down hill from there because Michelin switched to AS3+. Vehicle handled terribly and was likely a reject tire. It had balance issues 55-70 MPH and the mechanic obviously did not correctly torque wheel nuts because rotor on that one wheel warped in a few hundred miles.
So I was back in the hunt for tires and that AS3+ was very noisy on certain road surfaces.
I checked forums for this car and Taurus. There seemed to be a consensus that the Pirelli was a great tire. Softer riding and quieter. It might be a little softer on some surfaces but others it feels bouncy. Quieter, maybe a little on some surfaces. It does steer easier but does not seem to want to roll straight with every minor bump in road inducing sideways movement or even sway like the sidewall is not standing up. They definitely do not produce confidence like either set of Michelin. I ran those Pilot at 120 for about 30 miles on two lanes with hills and never felt them weak in any way. I have not run the Pirelli fast but to this point I'd be afraid to.
The Michelin were always great on wet, standing water, and panic stop. They were far better on snow than the same size Goodyear RSA on an 11 Lacrosse. I would not recommend that tire to anyone because I had two separate within 12K. It seems Goodyear has serious issues with tires staying balanced or not wear in unusual way. I considered Wrangler for my truck since that came on it. Dealer told me he would get them but his experience was that every time someone insisted he generally find one of four that would not balance properly. Talk at GM dealers and you find that Goodyear has lots of problems. Same issue with LS which they remade to LS2 and I'm hearing the same of RSA2.
The odd part in all this is I could have gotten the MXM4 cheaper than the Pirelli at the dealer.
