I'm planning to swap to Michelin Pilot Sport A/S 3+ around Oct 1 when Seattle enters 6 months of wet 30-50 degree weather.

About $1K from Tire Rack or Costco. Will give up a bit of sticky to have actual traction in the cold/wet.

I can't pull the trigger until after the new year but I am very anxious for it.

I just had no idea that performance tires had such low life expectancy.
The shorter tire life expectancy was a huge reservation for me prior to getting the car but have to say I find the Pirellis to me much better than the MPSS I had on my F80 M3...so much so, that I've decided to get the same exact Pirellis as stock for my replacement set. They make the car from my experience driving any where from 130MPH at 85 degrees to 100 at 15 degrees. They have really impressed me in a way that no other Pirelli or Michelin ever has before. BTW, I've got 6,500 miles on mine so far but think I can get another 6,000 miles on them.

The QV tires cannot be driven at temperatures below 45 degrees F. It's mentioned somewhere in the owner's manual.

Don't believe everything you read. The second week I had my car, the temperature fell to 15 degrees when I had to drive the car to CT to deliver some M3 mods that I sold to another M3 owner from NY. Once the tires were up to operating temperature, I was able to drive in Race mode fairly aggressively without a single inch of slippage while accelerating and turning. However, after parking the car for about 15 mins, they spun like crazy out of the parking lot, but then stuck like glue again when up to temperature after another 15 mins or so of driving. A notable thing is that was even with the tires inflated to 55lbs right after the dealership delivery prep over-inflation issue. I was as impressed with the tires then as I am now 6,500 miles later.

I am definitely not an expert on tires or rubber compounds, but I have been led to believe that the rubber in the Corsas can crack and degrade if it is flexed below 45 degrees.

Here is what Tirerack has to say about P-Zero Corsas by type:

https://www.tirerack.com/tires/tiret...jsp?techid=221

"It is not recommended to drive on these types of tires at temperatures below 40 degrees F (5 degrees C).

It is recommended these types of tires be removed from the vehicle and stored indoors at temperatures maintained at above 32 degrees F (0 degrees C) when not in use."

<Picture of a tire with a large crack in the tread>

Not all summer tires are this sensitive to low temperatures. Check the description of the individual model for more information.

Tirerack also says about the P-Zero Corsas:

A set for a QV Guilia is $1300, plus installation (typically about $250 for a high speed setup including disposal fees). Tax is extra.
The tires are hardness 60. Compare with the summer tires that come with the staggered setup on the 2.0T Giulia, which are hardness 220.

So I've got about 200 miles on my Michelin Pilot Super Sport replacement tires.....The car is significantly quieter and my rear diffuser is not longer being filled with every rock and pebble and cigarette butt on the street.....I get the Corsas for the track, but this is my daily driver and I'm in New York and winter is right around the corner....

Just curious of how bad this tire performs in rain or inclimate weather under normal circumstances. Every other car I've owned with these type of high performance tires I did not drive in inclimate weather. The Quadrifoglio is my daily driver, so I don't think I will be think about the performance of these tires everytime it rains. I don't want to hydroplane and find out the hard way. Would it be worth it to switch to all season tires during the fall winter season or just leave as is?

I have a heated garage (65 degrees in Winter), and tires very quickly come up to operating temperature when driven, even in low temps. I know this because my M3 measured individual tire temperature in addition to tire pressure via the TPMS. Unfortunately, the Quadrifoglio TPMS does not provide that info. The system is likely capable of it, but the software is clearly not activated to present it on the infotainment system. Pity!

Rubber cracks when left sitting in the cold (also caused by flat spotting) and not properly conditioned/cared for. Nobody is talking about driving Corsas in the snow, just on dry weather days to exercise the car's mechanicals in a way idling can't properly do. BTW...repeatedly removing and installing ultra low profile tires destroys them even faster than cold weather does, but it's not like the Corsas would last longer than a season anyway.

There is no doubt that other tire compounds are much better for regular low temperature driving, but switching to all season tires all year round is a far more extreme compromise that will ruin the driving dynamics of the car the other 8 months of the year and completely suck during snowy driving.

Dedicated snow rims and tires are the best solution during the Winter. Dedicated Summer rims and tires are best solution during the remaining months. My solution is to just consider getting a Stelvio around November for most Winter driving situations and only run the Quadrifoglio about 10 miles or so a few times a week on dry Winter days. However YMMV!
