Similar question to this thread:

I have OEM 20's, and am trying to determine what the most cost effective way of getting some snow tires.

I found some Pirelli Scorpion Ice & Snow tires that are supposed to work for the 20's, at about $250/tire. Do you guys think they'll still be useless since they're on these fat 20" wheels?

Or should I try and find some 18" wheel & tire combos? It seems like that's the more expensive route - putting me in the $1800 range?

HELP!!!
