Is this a good idea? Obvioulsy tyres will be dearer, and the ride slightly harsher. Questions is...... will the ride be hugely noticabley different?
Have many here changed from the 19" snowflake to maybe the 168M style? There the ones i've got my eye on.
If anyone has pic of the before/after wheel change, that'd be appreciated.

Looks and style are the reason for changing. If its what you want then it is a good idea. And like anything you really want, you will accept the slight difference in ride quality.
