I've never had a problem with any tyre "squaring off".
Of course they all square off and performance/feel might change slightly, but never anything worth worrying about and I can't understand why people get so concerned about it
the TA on the back of my 1190 is noticeably flattened to look at after 2000 miles of almost entirely minor back road use, but feels fine to me from the saddle.
