The narrower tires emphasize the Europa's strong points. First and foremost the incredible, telepathic and delicate handling. You think, it goes. Feel is amazing, delicate and communicative but not noisy and distracting. Fitting wider boots gives you higher cornering limits but at the expense of a loss of feel and a loss of that delicate interplay between car and driver.
Myself? I would argue NOT to fit wide tires -- at least not too wide. Unless you are trying to win on the track, what's the point? On the road, I get to drive at 8 or 9/10s, have a blast, and not spend a significant portion of my life incarcerated or having to drive only bicycles. Maybe you have self-control, not me!
