I installed these Pirelli Scorpion Verde All Season on my Mustang and I'm pleasantly surprised for now.
Dry grip is awesome, when I floor it tire spin is minimal above 4k rpm and cornering doesn't suffer much, coming from Kumho PS71 (UHP summer) there is slight understeer but the Mustang is nose heavy so nothing surprising, I expected worse and unless you push fast it's not noticeable in daily driving. The on-center feel is great and at the same time tramlining which Mustangs suffer from almost disappeared which is miraculous.
Wet grip is much better now, the rear always felt floaty before but it's now planted even during heavy rainfalls (it's spring rn) braking feels good (I also have upgraded Brembo brakes) and only when accelerating/braking over metallic joints or manholes you have to pay attention a bit but this applies to every tire especially in a Mustang.
I'll add details about snow/winter traction in the future when winter comes.
What really surprised me is the noise, the Mustang rides harsh so nothing changed regarding comfort, on the other hand these tires are super quiet, you don't hear them at low/city speeds and during high speeds (up to 200kph) they're quieter than the summer tires I had before. I was expecting a noisy tire considering it's made for SUV with lots of sipes but got the opposite, rides super quiet, Pirelli have always been the quietest riding tires for me and the Scorpion Verde AS is no different.
What I hope will be different than every other Pirelli tire I've had is wear, I managed to get around 30k miles with Michelin CC2, Bridgestone Turanza AS6 while Vredestein Quatrac Pro lasted me a ridiculous 45k miles... I never reached 15k miles with any Pirelli, in particular the Cinturato P7 wore flush to the wear bars before reaching 10k miles (those were OEM not aftermarket). Let's hope the Scorpion Verde AS manages at least 20k miles considering the 600 treadwear rating, we'll see.
