18's or 17's doesn't really matter. The price is the difference. As for wide tires..... stay with narrower tires. When was the last time you seen a winter rally where they use slicks???? Narrow tires cut through the snow/slush better and are easier to push through. I had Blizzaks before and they were good but I like my Dunlop M3's. You can't really argue tires unless you live in the same place. Tires good for deep snow suck on the dry days in the handling department. Here in RI we get maybe 4 or 5 days of good dumps of snow. We also get the light snow or slush a good number of days but most are just cold and dry. So when you buy your tires, buy it for your conditions.

 

Folks, if you search, I think you will find that it isn't so much wheel diameter as wheel width that makes the difference in the snow. The narrower, the better (relatively speaking. e.g. 215 is better that 245). Typically the bigger the diameter the smaller the height and wider the width (aspect ratio). One would think intuitively that wider tires would be better (example SUV's have wide tires) but it's the opposite with snow. Hope this helps. BTW, I'm from Quebec too....

 

^^^+1 Everything he said. The G handles like any rear wheel drive car with snow tires.

 

i think im gonna get the m3s for a 17in wheel, but anyone have a wheel sugestion?

 

Just make sure the narrower tires meet the same load rating at your stock tires or you may have issues. I know some 215s have lower load ratings than the stock tires so just be sure to check that before purchasing. I think its safe to go 215F and 235R, only 10mm narrower F/R than stock, which should be a good compromise between dry handling and snow
