I feel you on the PA4s. They have their strengths and weaknesses. As long as you can find a tire that ticks most of your boxes and you can accept or find your way from the unchecked boxes, that tire you chose will be ideal for you.
I went out this morning after clearing the driveway. Snow was high enough that any snow hitting the front bumper went up over the hood. Anything new and powder, the PA4s hardly flinched. It was once the snow got thick and squishy from others driving in it, is when the tires started to feel they had to start working for their money. As long as I got a slight spin in them they could grab and I just kept on throttle to maintain momentum. In a RWD, get used to going sideways with traction control fully off when you’ve turned from a plowed road into an unplowed road with deep heavy snow. You’ll need to control a slight drift until you’ve got up to your cruising speed. I’m glad this car uses rear brakes to fake out the open diff to semi-replicate an LSD so both rear tires grip and give me two-wheel traction vs a standard open diff / one-wheel drive.
That being said I think this tire is perfect for “my” needs and this car’s power output when there is no snow. As long as I pick my battles in the snow semi-wisely, the PA4s will reward with super fun controllable traction where residents shoveling their deep covered powder driveways will wonder how the eff I’m getting around in a lowered RWD German tractor whistling my way up a hill.
