What are you doing with your car?
Parking, checking views and smelling roses?
Spirited canyon runs?
Wider tires are heavy in slow daily driving/commuting, and difficult to park - as well as being hard on your steering box. If you run 205s, keep it rolling.
On the track, wider tires, 205x55x15's etc are VERY toss-able! Unless your Dougaling it around the track, or racing in a class where everyone is crippled with same tire rules - then MAYBE skinny are fun.
If you find wider, lower profile tires too "connected" - "not toss-able" - then push on the right pedal!
