14'' is 60 series tyres actually. I'm gonna change to 13'' wheels...downgrading the wheel doesn't mean poorer performance... I could increase comfort level and wider tyres mean more grip.

15'' rims with 175/50/15
14''  with 165/60/14
13'' with 185/60/13

Tyre profile are not correct. If they run 14s on 165/60, then on 13s it should be 155/70 to maintain the correct tyre profile.

Wider tyre does not mean more grip if you have taller profiles. The tall profile will negate the wider tyres as the tyre walls flex and lift the contact patch off the ground. In fact you would end up driving on less contact patch.
