Guys that ger Car and Driver magazine.

I saw this in the waiting room at the doctors a while back

I remember the article, but I no longer keep back issues.

From what I remember, they were adement to point out that their ratings were highly dependent on the type of car and size tire selected. And they said there really is no way to prepare a comprehensive test across the spectrum of available tires that would have any meaning across different types of cars. So the conclusion they can to basically said that for the tires they looked at for the particular car, in the particular sizes they ran, in the weather and conditions they ran, they ranked those tires against each other.

In other words, they were saying "ignore this test when you buy!"

Edit - Here's the article online:http://www.caranddriver.com/features/10252/tire-test-the-quick-and-the-tread.html

Edit again - After scanning back over that article, another reason to ignore their particular postings in that test pops up. Look at their #2 tire. It scored 3rd from last in dry performance (what 95% or Mustang drivers are after), but they put it there because it did OK in wet, and because . . . well they never really did describe why it ranks so high.

Basically what I took from that article was that tires are extremely unique and subjective to rank. And C&D lives on analysing and comparing catalogues of minutia of subjective differences among the best driver's cars - but still they were lost to distiguish articulately among tires.
