As you've most likely seen here
I've went down-size.
Rims: 13" / 5" Wide, 4-100, 43mm Offset - Steel Rims ($171, tax inc. new from Wal-mart) required slight modification at hub center opening
Snow Tires: GoodYear Nordic 155/80/13 ($178 tax inc. new on sale from Cad Tire)
So far I've noticed good driving characteristics, increased road noise
(obviously) and reduced gas mileage (again, obviously).
Thankfully - no snow on the ground yet here, so I'll report back on my original thread about snow driving characteristics.
