It would be a very bad thing to run 3 tires of one size, and a spare of
another. It would be okay to run like this on the front axle to get off the
freeway and to the next tire store, and the rear axle would behave as if it
was going around a corner and won't like it but it would not explode getting
you off of the freeway -- but could easily be damaged going more than a few
miles, I'm thinking the range of about 50 miles would be the limit.

You are correct though, the difference is under a quarter inch, and this
ought not be a huge problem. Having said that, my BMW had 205/60x15's on the
ground, and a 225/55x15 in the trunk. I had a blow out on the rear and the
spare caused the limited slip to make lots of noise. The difference in the
tire size is only .06", and this is only about 25% of the difference you'll
be having.
