I'm considering getting a set of 4 winter tires that will work front and back during the winter, allowing front-back rotation.

Tires would be 205/55-16 at all four corners. Rims are 16x6.5 +50 offset.

Will this work? How will this look?

 

It'll work and fit just fine- rear will be sunk in a bit in the wheel well compared to the front, but looks shouldn't matter for winter driving.

 

I ran oem prelude wheels that I believe are right around those specs with 205/55/16 blizzaks all around. PLasti Dipped them with some polished centers and was very happy with the performance and looks for what I had invested in them for a winter setup.
