[Resolved]  Tata Motors — tiago car tyre sidewall bulge

I had bought tata tiago in may, 2018 from malwa showroom prashant vihar. It is a authorized tata dealer. A tyre has developed side wall bulge. There has been no accident or any damage to tyre. The car has just traveled 6000km. I have gone to showroom few times but there has been no response/replacement from them. They keep on saying that this is bridgestone responsibility. On going to bridgestone they say that they won't replace it. This shows the poor quality of tyres used and tata's poor after sale services. I have maruti car and hundai car also never ever i have faced such an issue. Kindly address this problem.
