For the 14-years that I had my 156 Selespeed it was on the original size 205/55R16 and I never felt any need to go bigger.
Bigger would have looked better, but handling on normal roads would have been worse.
My TT however has 225/40R18 and copes very well on that size, better than the 156 did on 16" on rough/uneven roads....
Some platforms just don't work well with big wheels unless you get a very good spring/damper setup.
So if you live in an area with very rough roads, a lowered 147 on 17" is a very long way from ideal!!
