I had Yokohama DNA DB Made in Japan in my 2008 IDSI now sold...Must say drive was very comfortable...City's suspension be it 2004-2008 shape or 2009-2014 shape is not so bad...With any good soft tyres, the problem can easily be solved!!!
In your case, the problem is definitely with the tyres which are 50,000 km driven otherwise A-Drive are not hard tyres which make your car bumpier...Get any out of these for your next tyre change:
Dunlop LM702 or 703 not so high in price and Made in Thailand I guess, SP Sport 300 slightly expensive but the pleasure of Made in Japan is always there...Yokohama Aspec, Advan DB, DNA DB, A-Drive, C-Drive e.t.c are good valuable products from Yokohama...Michelin Energy Saver Series or XM1 and XM2 if you are interested in Michelin...Continental Eco Contact 3 or 5, Premium Contact 2 or 5 and CC5 if your budget allows as this is the maximum you can get for any car in Pakistan!!!
Now I have given you the complete list of good tyres which you can get for your car!!!
