The Brian Spilner ..... EVO

[scheides]

OEM size is fine. I'd recommend any of the following:

Nokian Hakkapeliitta RSi (best snow tire ever, hella expensive)
General Altimax Arctic (Nokian Hakka rip, second best snow tire ever, very affordable)
Hankook W409 (Nokian Hakka rip, not as good as the General and louder on dry pavement...still great tire)

The above are all kinda 'marshmallow' snow tires...epic in the snow and ice but on dry pavement they are a bit soft and marshmallowey.

'Performance' snow tires...made for sports cars, better in the dry:
Hankook w300 (great snow tire fo the $$, lots of people I know have run them and love them)
Hankook w310 (these are new version of the w300 I think?)
Dunlop Wintersport M3 (longtime great snow tire with tons of great reviews)
Dunlop Wintersport 3D (new version of the M3)

I will recommend the Generals to everyone; I had them on my evo and they are on my wife's GLI. They turn even a FWD wheelspinner into a fukin snow cat. That being said, I can't get them in 18" for my X, so I'm probably getting either the M3's or the W310's. If you can, get them mounted on a second set of stock rims and simply swap them on right when it snows the first time, that's what I always do. Otherwise, order them, have them waiting, and once the temp is consistently below 35°, have them swapped on.
