I have a 2000 323i non-sport package. I am looking to replace my 205-55-16 Conti Touring Contacts. I find that they have the lowest replacement price, but the Bridgestone RE 950 and the Dunlop SP Sport A-2 look more desireable. I live in Minnesota and have a dedicated set of winter tires and wheels that I purchased from Tirerack but still would like some snow capabilities in the replacement tires. What do you suggest. Also should I look to up-size to 225-50-16 on my stock rims?
