The 205/55/16 is the standard size for this gen altis in MOST - BUT NOT ALL parts of the world. If you generally drive on good roads this would be a good option. But if you drive on uneven roads, as most Paki roads are, you should stick to the standard profile 195/65/15. The tires are part of the suspension. The lower the tyre profile, the more the road irregularities are transmitted to the suspension resulting in increased stress on it..
