My Hybrid S came with 225/45R19 and 285/45R19 Michelin Pilot Sport A/S. Will I need to go to snow tires or will the A/S carry me thru the winter? Average individual snow fall here on Long Island is probably 2-4 inches. If do go to snows my preference is Dunlop Artic Alpine in 18" size.

 

Go with snow tires, the panny is a beast in the snow with them. I live in the suburbs of Chicago and run Michelin Alpin's on 19's and I get anywhere and everywhere. It is a cheap insurance policy for getting where you need to be. Dedicated snow and winter compounds plus siping works wonders. A/S tires just can't hold a candle to a dedicated winter tire package. I am sure there are those that will say you will be fine....but for a few thousand dollars in rim, TPMS, tires, you are protecting your investment. Plus there is always a secondary used marketplace for them in case you sell the car.

 

Is you Pany 2WD or 4?

 

My opinion is that you live in long island and it does not snow all winter.I think a good set of all seasons along with porsche excellent all wheel drive system should be more than enough.

 

Mine is all wheel, she is a Panamera Turbo. Regardless of rear wheel or all wheel, I always recommend snows in the snow belt cities. A rear wheel drive car with snow tires will perform better than a AWD car with all seasons. It is about traction and bite and siping and compounds. Your driving a very nice 100K plus car, investing in a set of winter tires and wheels is a no brainer. Having 100% confidence all year round is worth the peace of mind.
