I bought C-Drives for my car Honda City Aspire Prosmatec Silver in July 2013 in 195/65R15 size from a dealer on Murree Road, Rawalpindi named WELL DONE Tyres, the shop is quite famous and many people go there...Now the thing is that the date of manufacture written on them which is the embossed letters were 3rd week of 2012 means January 2012 means they were more than 1 and half years old...The tyres generally have no issue...Performing well but the only negative thing I noticed that they were not so silent and comfortable as even YOKOHAMA on their website rate the C-DRIVES 8 out of 10 in the silence and comfort section (ADVAN DB is 10/10 in silence and comfort) so 8 out of 10 is not a bad figure as whenever I drive my car on poor types of roads there is a strong noise which is caused by the air being compressed between the tyre grooves and the road surface and this noise irritates me a lot and the car shakes also on bad broken roads means to say comfort is less or the tyres are less soft!!!
Now on the other hand I had to get tyres for my second car which is Honda City Basic Manual in White colour...This time I went to ASAD TYRES in Saddar, Rawalpindi after watching the lots of positive response by people based on his honesty and the type of genuine stuff he sells, I got ADVAN DB and that too in 195/65R15 and he was again and again saying that the tyres are 100% fresh means to say that I bought them in December 2013 last year and the date of manufacture on them this time was 35th week of 2013 means to say they were made in August 2013 so they were not old and after purchasing them I noticed that they were perfect in all issues after driving them on the same types of roads on which I drove my car equipped with C-Drives and there was no that irritating air compression noise!!!
So my conclusion is and like Umair brother also says that always get tyres from a genuine dealer!!! 
P.S Maybe its my prejudice that the C-Drives are not so satisfactory and ADVAN DB is perfect but then why Yokohama rates C-Drives 8 out of 10 in silence and comfort on their official website...Can anybody tell me this???
