well i have general tyres in my mehran and i never changed tyres, i got those tyres with the car, they are still like new and i dont see any problem with the tyre, the road grip is very good, i am a very rough and tough driver, i agree with few members that for slower speed, within city, small cars general tyres are really good but for big cars on highway just dont put your life on high risk, get the best tyres.
thanks
