I am currently using Continental ContiPremiumContact2. I have used them for only 28,000 km in Islamabad. The front tires are in good condition, however, the rear tires are showing signs of wear, as the rear wheels were slightly misaligned. Just keep in mind that Continental's are made of soft rubber and don't last that long, especially if you have misaligned wheels. However, if you want good grip the highest ranking tires are Continental and Michelin. You can find many videos on you tube in which various top tires have been evaluated.
As regards road condition, Islamabad roads are worst of all major cities, the surface is rough, as no body bothered to re-surface these roads after Ayub Khan built the city. There are many huge potholes, and your wheels can get misaligned pretty quickly. CDA is only interested in mega projects, repairing city roads is not their priority.
