will running a 195/65/15 tire on rear of 2005 ford focus with a 195/60/15 on the other side damage the car
It will put some stress on the drive system of the car and steering of the car and handling will not be the same as if you had the same tire on both sides...
The Focus is FWD so stress on the drive train should not be an issue. The size difference is small but I would replace it with the correct size tire at the first opportunity you have.
