@incognit.. bro I am with you on that…
in fact I own a Liana too, but it’s a 1.6 A/T… not a single hitch ever since I had it in August 06…
As for the Dunlops.. I just said it coz 2 of my cousins had them and also a few friends and they all said that it swells from sides… I have myself seen one… maybe they have overcome this problem and new tyres doesn’t have it… I am sure you have done your home work before going for those 
Take Care..
