It's better to use OEM recommended tyres, other wise 215-55-16 is close alternative to 195-60-16. It will only increase vehicle height by 1.25 mm which is acceptable. It will be 20 mm wider and 1.25mm higher then stock tyres. With wider tyres there will be more friction and would slightly decrease fuel average.
On the other hand 205-60-16 would be 10 mm wider but will increase height by 6 mm. With these tyres you would have almost same fuel economy but would compromise on vehicle stability.
So as per my recommendations go for stock tyres or buy 215-55-16 as close alternative.
