My 2 months old car has a bulge in the left rear tire. Help me understand if the tires which are placed are not for Indian roads? Because its a new car which ran just 4000 kms & tire already has an issue at 4000 KMs and the dealership says its not BMW quality issue & I need to bear the cost. How do you measure the quality of your vehicle? I am based in Delhi & not in a tier 3 town that there are no roads around.
