Snow Tire Sizes..

Hey folks-

My dad has a "connection" at a local tire store, so he and I went in this evening to pick up my brother's vehicle and get a quote for snow tires for mine.. Here's what they said:

In the interest of saving money and putting a slightly narrower patch on the road, they advised I go with a 205/55 R16 tire. They told me that they could get Accurate (Akuret? it was some funky spelling) Grip tires on all four corners for $300 installed. This sounds like a frigging FANTASTIC deal compared to Tire Warehouse quoting me a MINIMUM of $460..

Doe sanyone have any input on the smaller size?
