You are going to love the Pirelli's in the winter and snow. I am one of those who purchased the Scorpions in stock 20" sizes (275 and 315) last year and swear by them. I swapped them back out for the Diamaris' that still have good tread left for the spring/summer/fall use. I like max performance of two sets of tires that are dedicated to their specific seasons.

Winter tires can be a little noisier but some summer tires are not that quiet either. My diamaris in the front are fine, the rears are toast, but both ends make ahorrible racket....

I run winter tires (X-Ice) on my Tundra year round coz the rear axle has zero grip on summer tires (unless loaded ofcourse). They have over 30k miles and another 5k on them easily.

I also drove my Dunlop M2s one summer when I broke my foot and didn't feel much like swapping them (I have dedicated wheels). They wear quicker in the summer for sure but unless you track your car you are not giving up much, if anything.

In fact, summer tires or all-seasons in the winter is horribly dangerous and I see it all the time around here. The latter situation is FAR worse in my book as you may be able to gather some speed in a 4x4 but you will NOT be able to slow down.......which is witnessed by the incredible number of SUVs that wind-up with the shiny side down :-) around DC.

You don't think you are giving up grip by using winter tires in the summer? Really? :confused:

you certainly do give up some grip. But I don't think it creates a dangerous situation. Not on the order of running summers or even all seasons (no seasons!!) in the winter anyway. I run them until the rainy season is mostly over because my summer tires are pretty dicey in heavy rain. And we get some warm days in there. Never noticed an issue with grip although I am not trying to lay down top time of day on an autox course or anything :D

I am not saying it is more dangerous than using summers in winter. I wouldn't suggest doing either as they can both be dangerous. Put on the right tire for the right season. They were designed that way for a reason.

fseth, great point about the temperature. where is the comparison that specifies the temperature that the test was done at?

I can't find the video right now. I will look tomorrow. The only one I could find was comparing winter tires to summer and all seasons on ice, which is not only affected by temperature, but tread pattern as well. I will try to find one based soley on temp. In the meantime, here is a chart stolen from one of LeMansX5's threads;

don't work too hard on it. I only asked cause I have never seen a comparo that states temperatures. even Consumer Reports doesn't tell the temp they test at. (then they say winter tires don't do as well on dry pavement, duh, of course not at 70F!)

We use winter tires on each of our vehicles even though we get about 3 days of snow per year. I think the temperature alone has a much bigger influence on winter tire benefits than many give them credit for...

Sorry sprocket, I can't find a video on Tirerack's website showing dry testing. All the tests were on ice or snow. I think that I confused one of those for just testing based on temps.

The above chart I added from LeMansX5's thread was from BMW Canada and the following link is to Continental's website. Both suggest that 7 degrees C (44F) is the temperature cutoff.

Just about every tire source says that the summer and all seasons harden at lower temperatures (below 7C) causing poor performance and that winter tires in hotter temps get way too soft to perform well. Plus, they wear very quickly.

Ofcourse winter tires are not ideal in the summer which is why I have a set for of each kind. But, if you are going to compromize on a single set of tires in a place where temps drop below freezing or a lot of rain around freezing then winter tires are a perfectly acceptable compromise. No further comment.
