What you guys aren't cosidering is the lower profile of the wider tyre. As the profile reduces, the tyre lowers it's chances of the sidewall flexing under hard braking, this makes sure that the wider (lower profile) tyre retains a larger percentage of it's contact patch when subjected to braking forces.
When rolling, the diff in contact path maynot be much but from my point of view, this is a good thing as it doesn't affect the rolling resistance of the tyre.
C'mon guys, do you really expect a 165/80 R13 tyre to provide as much traction as a 205/50 R15 (on the same car with the same tyre pressure)? It's just not possible!!!
