You don't want to have to recalibrate it again next sprong when you put the summers back on.. As far as the tire size, you went the WRONG WAY, anyways. You really wanted a set of something closer to 205 70 tires for the winter - a tad larger diameter, and NARROWER.
Even better yet, something like 235 70 15 tires on 15" rims. (I didn't check the actual tire interchange for equivalencies, but it should be close and shows the direction you SHOULD be going. High profile narrow agressive snow tires on the smallest diameter rim that is available for the car - with rolling diameter either equal to or slightly larger than the factory tire. Particularly on a vehicle with anti-lock brakes.
