Not sure the results are 100% accurate, I have a bunch of questions regarding the test.
-What order were the tires tested in?
-what time of day were they each tested at?
-outside temp during each test?
-why is there no video of each independent test?

I guess I find it hard to believe that the dunlop was faster then the other popular tires most fast auto x cars are using. its also weird that the winning Tire happens to be a tire that tire rack sells.
