I think they have the chart labeled incorrectly. The gray shading in the middle is the "average" of all the tires in that particular test. The lines represent the relative performance of that particular tire in comparison to the others. So 101% means that tire performed 1% better than average. 99% mean the tire performed 1% worse than the other tires. If you dig into the test report, you can find actual numbers.
Both tires are almost identical. Pirelli's Scorpion series are for trucks and SUV's because they have a slightly stiffer sidewall to handle heavier loads. That said they are not as sporty as the P Zero AS Plus 3. EITHER ONE will work just fine on the Mach-E and they will both be as quiet. The P Zero will be a bit more comfortable than the Scorpion.
Thank you. I was looking for the other posts where you had the upsizes that would fit a ‘21 Premium AWD with the 19 wheels but couldn’t find it. Can you share the upsize possibilities from 225/50R19 which fit? I have no other changes such as springs, etc.
I would run 245/50/19. The factory size is actually 225/55/19 103
Your OEM tires should be 225/55R19 not 225/50R19, correct?
UPDATE: 3,000 miles in I am still very happy with my Pirelli P Zero AS Plus 3 Elect tires. I have had absolutely no issues on wet roads. But on a recent trip between Toledo and Dayton, I encountered light snow the whole trip. I-75 was mostly clear but some stretches were questionable and on those stretches, I could feel a little play in my steering wheel, but my Mach E still tracked straight and true and never gave me any indication that I might lose control. So, maybe it was my mind playing tricks on me.
I've had both. I did upsize the Scorpions to 265/40/20's. The PZeros are quieter and a touch softer. However the biggest complaint I had with the pzero's was the leakdown. For about the first couple months the tires would lose about 2 psi a week. No leaks, just all 4 would drop about 2 psi a week. (Iit wasn't environmental factors either as I'd been on vacation for 2 weeks several times and would just watch them lose pressure while it sat in the garage.) They also would heat up and gain a bunch of PSI as well. I could leave the garage in the morning and be at 36psi. 5 miles later in ~100 degrees they's be at 41psi. Later that day nearly 43. This was pretty much impossible to target a psi to keep the car riding the same. To low and you'd get a double bounce from the rear as the suspension wasn't rebounding as fast as the tire wanted. On the drive home I was on those concrete Roman tires. They had better road noise suppression though.
