Leadfoot is on a distinguished road

I run 195/50/R15 which I calculate has a total diameter of 576mm.
195/55/16 calculates at 620.9mm.
This is a difference of 44.9mm or to put it another way, your wall height from the wheel centreline is 22.45mm more than mine which, depending on ride height/spring/damper settings could be part of why your wheel/s are rubbing.

Also note that there is a 4.4mph speedometer difference if you go to a smaller tyre (if I've worked my maths out correctly).

I can't understand why one side in particular is an issue unless there is a difference in bodywork or the rear is slightly offset (mine is...)
