My plan right now is to hit up the junkyards for a set of 15" (steelies if I have to) rims. Reason for the small size is I can run 205/60-15's on them, and the local tire place has a set of Cooper winter tires, H speed rated for $80 each installed.
I guess the SVT will accept 15" rims with stock brakes (I saw a pic somewhere of an SVT with 15" steelies and hubcaps...)
I think I'll be rollin ghetto this winter, but I'm not worried about it. (I'll post pics...

)
Come spring, I'll be replacing the Kumho Ecsta 17" (they're pretty worn out).
