Hi
I have an Avant TDi 170 with 235/45/17 tyres.

I have some good michelin winter tyres which I would like to fit. However, these are 205/65/15. I can get some suitable wheels for this, and the ride will obvs be more bouncy, but has anybody any knwoledge of what fitting somewjhat thinnner wheels will do to the handling?

Thanks
