Bridgestone Tyres India — Tyre warranty defects

Address:

Madurai Tamil Nadu India

I bought TATA Nexon car on 28/10/2022 from Chima show room at madurai .On Nov 3 2022 my car front left tyre became flat and I the same shown to TATA service and sent to Bridge stone company .The tyre got outer side wall crack and they say it is not warranty defect .
But I am as owner very much sure never hit the car tyre side way.I am saying it is due to rubber quality that’s why cracked .
Now bridge stone says that it is not warranty defect even though the defect happens within the warranty period.
Now bridge stone tyre company refusing to replace the tyre with new for free of cost
They are keep on insisting it is not warrant defect
