Mahindra & Mahindra — Poor tyre quality

Address:

Chennai, Tamil Nadu, 600016

Dear manager,
it gives me profound displeasure to write to you for dissatisfaction in the vehicle xuv 500, of which i took extreme pride in being an owner.
I bought my vehicle with extreme passion to your brand and quality which is supposed to be associated with your brand name.My vehicle is a single hand self driven vehicle withextra caution and compassion.Within 15 months of driving and merely 8000kms of distance driven the vehicle is showing up trouble.Infact within 6 months one of the tyre showed a leak off and on.Doring my first service i brought this point to the service mechanics and the noise from the tyre and leak was probably halted for sometime.
But after a gap of 5 months when i was coming back from a trip the tyre midway just gave away and flattened so badly that it could have led to something awful had i been cruising at a higher speed.
Now after having shown it to couple of tyre repairers i am being told that this tyre is finished and just cant be repaired.The piece of tread from the centre of tyre has come out and the sides of the tyres are so weakened that they are balooning up at places on inflating.
Plz sugest what am i supposed to be doing in such a scenario.I expect you to give a considerate look into this case and suggest a viable solution less i raise the level of grieviance.
Looking fwd to hear from you asap.
Regards
