C drive 185/65/15. Will give you ample clearance with good roadgrip whilst keeping within the 3% differential value. Value above 3 will affect the car's suspension hence avoid 195/65/15 at all cost. 195/60/15, on the other hand, has a differential value of under 2 and will give you good traction on paved roads but the ride will be bumpy on dilapidated roads. In my view, the 185/65/15 is the ideal choice for your City.
