Bridgestone Tyres India — complaint about newly purchased tyre-small crack developed

Sir,
Sub:- Complaint about the newly purchased Bridgestone tyres.

I am an engineer working in Kerala Government Service. I bought two Bridgestone tube less tyres (165/80/16 S248 TL) from your dealer M/s Tyre Tech, Polayathode, Kollam, Kerala on 12.09.2017 (Invoice No. 112 dated 12.09.17) and found that they were durable and comfortable. When the other two tyres in my car (Ritz- diesel) were worn out, I again purchased two more bridgestone tyres from the same shop (Invoice No. 434 dated 30.03.2018). These two tyres I used as front tyres as they were new. Moreover the dealer had given me three years warranty also.
But on 06.07.2018 when I was coming from Trivandrum to my house, I found that the front left tyre (new one with Serial No: CHE 4917) had lost its air and found that it had became “Punchure”. I was surprised that the brand new tyres, only 3 months old had a small crack on its left face. Next day I contacted your engineer (Mr. Sanil Hammed Kufti) at Trivandrum. Last week I got a letter from him showing that the damage was due to the side wall cut penetration by some external sharp object.
I am surprised to hear this from an internationally branded tyre company. I guess that there may be small crack even before purchasing the tyre and it might have developed during the long journey.
When I discussed this with my friends (both Engineers and Advocates) showing this crack, they advised me to contact the company directly. We have more than 9 cars in our family and all these people are using “Bridgestone tyres” for long time.
So I request you to do necessary steps to replace the damaged tyre with a new one without any cost.
