WORN OUT TYRES

Good day<br> <br> i purchased an Audi A4 from S4 auto and delivery was on 02 April. before delivery i asked Riyaad that if the tires of the car are not in a good condition then i'd like to have them changed by the dealership before i take the car and on the day of delivery he showed me some paper which had 77 written somewhere on it and said that the 77 indicates that i still have 77% life span on the tires but that 77 was not even written on the section of tyre checking. just last week i went to tiger wheel for alignment which Riyaad had assured me that he took the car to a dealer that confirmed that the car needs no alignment at the time of purchase, when i fetched the car from tiger wheel later that day the technician there told me that two of the tyres in that car were purchased in 2012 and are in a very bad condition of which they'd have to be replaced within a maximum of two months. when i contacted Riyaad last week he mentioned that there's nothing they can do because i've already driven 3000k's since purchase. there's no way that a car would go from 77% life span of tyres to \needs urgent replacement"in just a period of two months after purchase and only 3000k's driven on the car."""
