i think 205/55/15 is the most odd size tire available in Malaysia Market.
For michellin mxv8, yes you can get new but OLD tires, way back in 2002 or 2003.
For michellin preceda, michellin themselve no bring in to malaysia. but you can try spore.
For other brands, you just need to search high and low. But then again, it will be old stock.
The best bet is still the G3 which is just ok for your normal drive.
