I thought those lap times were for the specific tires being tested against each other only and was not an accurrate way to compare other tires on Tirerack that were not a part of the test. I thought I read that somewhere on their site. The ratings were also tested for a tires specific class. If a Max Performance tire scored a 7.5 in handling...that score represented how it ranked in the Max Performance category only. An ultra High performance tire may score a 7.5 but that does not mean it is as good as the Max performance tire because they are rated per class.
If this wrong please correct me...but I remember specifically reading this so I did not compare tire ratings unless they were tested together and in the same class.
