I bought my new Maruti brezza car Navneet Motors Udaipur while purchasing the car I bought zero depth insurance and and while purchasing they sad.. in the cover till 40000 kilometres for tyres included.
But after only 10, 000 kilometres in the period of one year unfortunately 2 tyres of my car burst.
