Pirelli P Zero System vs Michelin Pilot Super Sport — Compared

“I use mine all year round, and it's only in snow that they come unstuck - although I've never actually been driving in enough snow to need to break out my sno-socks. I've done wet 'Ring laps on mine, below zero Welsh hoons etc. They take about 10 miles to warm up enough to push on, but you probably shouldn't be pushing on in the first 10 minutes of a sub-zero day anyway!”

“Had this on my E90, as well. Alignment was good, wheel balance on road force machine was good. Turned out i had over 0.250" of runout on both rear wheels. Took me two sets of 255/35/18 PSS's and me watching them balance the tires to figure it out... bought new wheels, never went to a Tirediscounters since.”

“Our 2017 Z51 has about 18k miles on the AS3+ ZP, and 10k miles on the factory PSS ZP, we switch out every Fall/Spring with a second set of wheels/sensors. I've done hours of really hard driving on back roads in Texas and New Mexico with the AS3+, if you need the little extra grip of the PSS on public roads, you're driving like an idiot. I only keep the PSS because I do some autocrossing each summer and small increases in grip can be the difference between good times and mediocre times. Also, the PSS will stand up to the heat of competition driving better, but that shouldn't be an issue on the street. The PSS cost about 10% less and last about 50% longer, so your tire-cost-per-mile gets cut in half. Below about 50'-60', the AS3+ grip as well or better. I just tested them in 3 1/2" of snow on my driveway, worked pretty well. The AS3+ should be the standard factory tire, with the PSS only as an option.”
