The only good tyres introduced by Dunlop are Dunlop SP Sport 9000 and SP Sport Maxx. All other tyres are either notorious for various sorts of complaints or are not good value for money. And you do not get SP Sport 9000 and Maxx for smaller cars like cuore/cultus etc. Also anyone who thinks Sp Sport 9000 is a hard tyre is grossly mistaken. It is a soft tyre. Infact in the local market dealers 95%+ of the time only import soft tyres (in 15") because of the Goodyear f1 and Dunlop FM901 which were very hard tyres and ruined suspensions of most cars. Afterwards dealers stopped importing hard tyres.
The ones you got installed are Digi tyre/Eco 201. The tyre is extremely soft with weak side walls and is the most notorious tyre in the market as it easily develops bubbles in the side wall.
In your case (cuore) I would suggest going for Good year GPS 2 or Ducaro series (Made in India) or Yokohama A drive. Personally I like GPS 2 much better. Awesome grip and comfort with medium strength side walls which are ideal for our local road conditions and do not develop 'bubbles' in them on hitting potholes
