Pathetic tyre on road . Review on Tyre

This is nitash from india , i purchased a getz car 7 months back from himavasini hyundai showroom in hosur tamil nadu, the tyres which came were good year, after couple of months one tyre were getting puntured very frequently and when i had to visit other place which was 600 kms away with my family the tyre got puntured again and again , i hope you can understand the difficult situation i faced with kids on road searching for puncture shops finally i reached the place and checked with hyundai people they asked me to show in the showroom , from where i purchased vi came back to hosur and went to hyundai showroom and showed them the problem, they asked some engineer from good year to come and he inspected the tyre and told that he will be getting back after contacting his higher authorities , but till now no result has come the hyundai dealer is telling me that it cannot be replaced , i want to know when that it clearly shows that tyre problem why cant it be replaced and more over the second tyre got puntured within two months of car purchase that too not even 500 km with a thick screw , see the condition of tyre i am shocked to see how a thick screw of 3 inch peirce the tyre and the engineer says we cat guranetee even for 2 km , i used to use mrf in the other twio cars they are excellent even after 10, 000 km in ford not even a single puncture , but in this getz its terrible i will suggest all my friends buying any new car dont ever go for good year its waste
