Great Drive But Tyres Are a Big concern

Just got my brand new Benz exactly 2 weeks ago . The drive is great . Interiors is 5 star; exterior is classy. Showroom service could have been better in the initial stages when I had not yet fully decided on the vehicle . But the biggest pain point has been the tyre's . Made by Pirelli . We had just two drives - Sunday date of delivery from Auto Hangar Prabahadevi to a Matunga temple to home in Bandra , and the next day Bandra to Everard Nagar Wadala and back . Day 3 afternoon we were all set to go out and behold we had a flat ! Our puncture service saw one nail had done the job . I am really alarmed that such a beautiful vehicle otherwise is riding on sub standard tyres . Driven an Innova for 15 years - we got our first flat on a long drive and back from Kamshet on very rough roads . I asked Benz to replace it , while they first said no , I had to mention I will be providing an online review soon , I soon got a call that it will be replaced . Instead however we were asked to take it to service center only to be told the there is nothing wrong with the tyres . Well , in city if one nail can give a flat tyre , then I shudder to think if tyres were to be so vulnerable then we will have a forever traffic jam . I have expressed my disappointment and await further word from their customer service . I also plan to totally change all the tyres soon before a planned long drive .
