After driving for few days i noticed that some echo type sound is generated. I showed to dealer and mechanic, they found nothing wrong with my vehicle, and it is observed that it is tyres that are creating that sound.
My request is plz.Look into my complaiand replace the tyres because it is my hard earned money and with faith in ceat company i purchased tyres.
