I drove a 2002 Z/28 with all seasons for 6 winters in Virginia. Tires make all the difference.
At one time I had the Falken Ziex 512s (not even available anymore) in 255/50-16 on the factory 16x8 'snowflake' (named so because of their spoke pattern) wheels on my 2000 Z28 LS1.
Previous to this, and the first month I owned the car new, I had pure winter tires on these wheels, either Pirelli Snow 210s (I believe), or the Michelin Pilot Alpins in a 225/55-16 (both LONG gone models now).
But I got tired of burning these expensive winters up on the 95% DRY, but yes, still cold roads, so I regrettably tried those Falken all seasons, which also had a horrible tendency to develop large sidewall bubbles as well, from even the slightest pothole hit.
The BFG g Force Super Sport all seasons (the also now gone precursors to their current g Force COMP 2 all seasons) I had on it right before selling it were actually VERY impressive in light snow, and cold winter ambients,
despite their 245/50-16 size.
It was snowing at a good clip with about a half a foot already on the ground, and I was trying to get to my kid's varsity hockey game.
There was one steep hill (out in western north Jersey where the rink was) that the Z28 just COULD NOT get up with those (almost full tread depth) Falken all season tires on it, despite having an Eaton Posi clutch pack type limited slip in the diff, AND about 100+ lbs. of kitty litter right over the rear axle!!
The car just started going 90* to the curb sideways no matter what I did, or what gear the T56 was in.
I had to turn around and go back home, missing his game.
The Potenzas not even being that great, and a VERY dated, pure summer tire was WHY I ordered THIS car with the PS AS/3s on the Rados from the factory.
I figured they can get me through a few winters until I can afford a pure winter wheel/tire setup, and I was getting a pure summer aftermarket wider wheel/much stickier tire setup than factory no matter what, the first spring (last spring) I owned the car regardless.
