To preserve speedometer accuracy 205/55-14 is better.  Audi already
err'ed a little large on the aspect ratio of the 4kq's stock size (195/60-14):

Specification  Sidewall  Radius  Diameter  Circumference  Revs/Mile  Difference
175/70-13         4.8in  11.3in    22.6in         71.1in        891        0.0%
185/60-14         4.4in  11.4in    22.7in         71.4in        887        0.4%
195/60-14         4.6in  11.6in    23.2in         72.9in        869        2.5%
205/55-14         4.4in  11.4in    22.9in         71.9in        882        1.0%
205/60-14         4.8in  11.8in    23.7in         74.4in        852        4.6%

The first three are all stock sizes on the 4k series cars (first two on
non-q).
