Hankook, Dunlop & Bridgestone, are much common on Mehran. I don't know much about tires, but have heard that Hankook, especially Optimo me04, are much good for making the car ride feel much 'Comfortable'; Dunlop, eco(I think), are soft and give good mileage; and bridgestone are hard, not as much as General one's that u got, but last long.
I recommend Hankook Optimo me04, as I took a ride once in an FX( having suspension very similar to that of mehran) and it was the most comfy FX I could remember ever riding on, although it was a Taxi. Since that I am a fan of Optimo's.
