225/50s and 225/55s are the same width........225mm.
I'll assume you meant 255/50....that would be wide.
255/50 has a sidewall height of:
255 x .50 = 127.5mm
127.5 / 25.4 = 5.02"
225/55 has a sidewall height of:
225 x .55 = 123.75mm
123.75 / 25.4 = 4.87"
(that's why steering response is so good)
215/60 has a sidewall height of:
215 x .60 = 129.0mm
129.0 / 25.4 = 5.08"
The 255/50 and the stock 215/60 have an almost identical sidewall height.
But, the stock 6" wide wheel pulls the sidewalls in too tight and therefore
they are not in a "natural orientation". That's the reason for the mushy
turn-in.
