We don't get a ton of snow here
But, my daughter has spent 3 snowy winters in the NC mountains....her last is this winter. Graduating college!!!!
She has a 00 Maxima and I put Yoko Envigors on it last summer.
Had Yoko Avids on it before the Envigors.
BOTH did very well in the snow for her!
She is a graphic design major so she has to get out in the snow a lot for supplies!!!
She drove when her friends wouldn't.
Currently thinking about either Envigors or Yoko YK580's for our G35X.
Yoko sells YK580's to Discount Tire. To see info. on them SEARCH YK580 on Yokohama's site. They don't just come up when you plug in your car.
I currently have the Conti DWS on my G35 coupe....coming from Yoko S-Drives, not as happy with their at limit cornering, but they do go in the snow!!
DWS's are rated very high with Tirerack.com too.
