If your wheels is 16x7JJ that ori tyre 205/55/16 is correct spec. Do not buy 185 or 195 because the tyre will be stretched a little because not wide enough. That means if you corner, the tires will lean higher on the sidewalls. Maybe can consider Viking.

Still cost over RM200. But its not china tyre. Made locally by Continental.

Another option is find original Merc 15" wheels 15x6 or 15x6.5 so you can use cheaper 185 or 195 tyres.

You gain some comfort and some fuel economy. But loose some handling characteristics of wider tires.

I have used budget silverstone on myvi and old corolla before. But viking is far better than silverstone.
