Tires MICHELIN or OEM Porsche

Michelin premieres perform great in the snow, about as good as winter tires (reviews on tirerack) Turned my prius into a beast in the snow (for a prius).

I purchased Michelin Pilot Sport All Season 4, from Tirerack, my god they are better than the ExtremeContact DWS tires (which I used for 8-10 years).

The defenders are all I ever buy. They will rot before they loose tread lol.

I've used Michelin Defenders for years and have been very happy with them.

Michelin tyres. They’re one of the most reassuring in wet road conditions. The car behaves predictably in heavy rain conditions with those tyres fitted.

I have cross climates on my truck and I can't believe how good they are. It's the first time I've ever been impressed with a tire

Given that you live in Toronto I would say Michelin Defender. All season tires, but absolutely amazing in snow.

Michelin pilot sport 3+. Great grip and good in Vancouver rain.

I have been riding on them for about 11,000 miles. 2018 GSW SE. Excellent tires so far. Properly inflated, not loud at all but do have a low grumble that is not bad. Fantastic wet tire. They remain planted in the rain and give good secure ride. Ride more like summer tires on dry pavement, cold or warm weather. Great ride I am in Wisconsin and they are superior to all seasons in snow, although nothing compares to true "snow" tires. I've driven in some pretty good storms and they are definitely sufficient for most conditions. Will slip in snow a bit here and there, but give plenty of traction for acceleration and braking. Ice... be careful, regardless, and these are not studded tires. I highly recommend them for all season driving, including right through the snow.

I have Michelin Xi3's. I can't recommend them if you care about your car's performance at all. If you don't GAF then these are fine. Probably ideal for a Prius. They work fine in snow, the brakes work on ice, and the ride is alright. That's all the praise I can give them.
