Why would anyone have 205/60 on your car and that too Dunlops, no wonder you're complaining.
Get Yokohama Advan DB or Michelin XM2. Go for 195/60/R15 or 185/65/R15(recommended).
I have 185/65 Michelin XM2's, they improved the car average from 13.2 Kmpl to 14.8 Kmpl within city.
Price in islamabad/pindi ~8000 per tyre for UK imported ones.
