Tires BRIDGESTONE or OEM Porsche

I have a 2015 GSX-S750 that I've run Bridgestone T30/31 for many years. Solid dry performance, decent wet grip and long life.

Blizzaks.

I recommend Bridgestone Weatherpeak (Subaru Ascent).

I've been running Blizzaks (WS80, then WS90) on the stock wheels on my '18 Sportwagen since new and have loved them.

I bought the Weatherpeak 2 years ago. They were great tires in messy weather. No complaints at all there. But they wore down very quickly. Like in 25-40k.

Bought Weatherpeaks instead of CC2 for our Crosstrek, no difference in MPG. They're quieter than the stock Falkens.

Snow traction isn't as good as dedicated winter tires but it's good enough for the winters around here.

If you need dedicated winter tires, best option is to buy a second set of rims and winter specific tires, Blizzaks are a personal fav of mine.

16k miles and I’m down to 6/32 secs with my Weatherpeaks.

The ecopias are garbage.

Ran the blizzaks through 4-6 inches of snow and was barely making it through that. I never had less confidence in the snow than on those WS80 blizzaks. They were almost worse than the Sotozorro 3’s I had on my R two winters ago. Those I’ll excuse those because they were at least OK in the dry, otherwise they were pretty terrible in anything but light snow.
