Tire Sizing Questions (Total noob looking for winter tires)
 

I'm looking at picking up some Blizzak WS80 tires for this winter and to be honest, I just don't know what the hell to go with.

I'd like to have a little more sidewall than the stock tires do, but I also don't want to have issues with rubbing the wheel-well or anything.

Would something like a 215/55/17 fit correctly without rubbing, or should I go down to a 16 inch wheel for winter and get something like 215/55/16 or a 215/60/16?

I really just don't know what sizes are appropriate for our cars.

TireRack usually offers a bunch of models in 205/55-16, which would be the correct size for use with a 16 inch wheel.
