Toyota — Defective Tyres fitted in New Crysts bt Toyota/Local Dealer

I m having the same problem my rear tyres got burst at 32000km 215/55 r17 bridgestone turanza car is just 6 months old. Bridgestone and toyota local Bilaspur deal JD has rejected my problem by saying Toyota not giving any warrenty on tyres . i think these tires are not compatible with innova new 17 inch alloy. If everyone is facing problems.
Recently within last 7 days two rear tyres of my vehicle got air bubble and had a cut at same place as well as same type near alloy disk edge (where tyre number is embossed). In this scenario all 5 tyres may get defective in coming days.
It is very surprising and unbelievable that within 6 months and 32000 Km running both rear tyres got defective in the same manner due to air bubble and it is not repairable.
I feel that this happened due to (1) Before delivery of new vehicle J D Toyota has replaced original company fitted tyres with defective one. or (2) Toyota company had fitted rejected/ Faulty /defective tyres in new vehicle or (3) The whole lot of tyres fitted in new vehicle was defective.
I believe Toyota is a highly reputed brand and never compromises with its product quality and customer services. Hence I request to you and your company to kindly replace all 5 tyres with new ones under warranty.
