Bro i have been to both the shops, everyone has their own dealing, it all depends who you prefer. United Tyres, Unique Tyres, Discount Tyres are all well experienced shops and they are have experience of decade or more in this field. Similarly there are a lot of stories associated with them as well. I've heard United Tyre sell tempered tyres, Unique guy has a bad temper etc etc., but as long as you know what you are buying no one can sell you a counterfeit.
What story we choose to accept is what we buy, and then offcourse the price. Michelin you mentioned are coming in import and the price of import is 8000 and if you call in karachi you will get above 8000/tyre, but we are not willing to pay offcourse 8000 because we are getting the kabli/afghani tyres in much cheaper price so we choose to pay for that, but that doesnt mean one shop is right and one is wrong, its what we choose to accept.
Last thing i would like to add, as far as the you trust is concerned you choose to trust a shop doing false marketing and selling kabli tyres under dealership tag and the story between their relationship (fact is Japan-tyre guy worked as a salesman for Syed Talha Ahmad, Discount Tyres) but not what DT guy said.
and By the way we got continentals 2017 yesterday form Discount Tyres. Why because he speaks his mind, tell me the real truth behind the channel of tyre and always give preference to me (customer) over selling his tyre.
