Arite. One of the detailed reply I just wrote somehow got deleted.. :s
Here it goes again (well, some of it :D)
Thank you very much Umair for the reply and suggestions. Unfortunately, I could not read that and went for the tire change. It is quite a long story but in the nut shell, I went for Advan DB v551 in 195/65R15 Size from authorized reseller of Yokohama.
It all started with Continental CC5 in same size, which I had to remove after installation of front two tires coz their country make was tempered and I lost the trust there. Then I had to select between XM2 and Advan. The salesman somehow convinced me on Yokos. 195/60 is hardly available with the shops here and if we find any, they are quite old tires in terms of manufacturing dates. Plus every local tire dealer tries to convince that he is selling a better thing than others.
Khair, MashaAllah the drive is prettttyyy smooth now. It feels better than a stock city and in control. Also I am aware of the fact that if I don't drive carefully, these huge tires might damage the suspension. 195/60 is the ideal size but I am that kind of driver who literally stops the cars at Cat-Eyes and Road Damages. Let's hope that it stays well. Plus its quite a soft tire so the hardness of the suspension feel somewhat softer now. Another major change is the look of the ride and I am posting a picture for your reference.
All I have installed is the window blinds and the door visors.
