Maruti Suzuki India — Poor quality Tyre on new vehicles

We bought a ertiga 4 months ago, and today a small stone get inside of Tyre from middle of Tyre resulting flat tyre on middle of a road . And now the company is ignoring us by saying the Bridgestone company tyre they provided with car it has no warranty, I mean, dose it make sense to buy 13 lac vehicle and you got your Tyre cut because of poor quality tyre you need to buy new one . feels like waste of money
