Post-Race
Two days following the running of the race, NASCAR VP of competition Robin Pemberton formally apologized for the problems, saying that it didn't go to IMS with the correct car-tire combination. To rectify those problems, Goodyear staged two additional tire tests at Indy in the fall, the first with only three teams as per the tiremaker's policy September 22 and 23; the other with as many as 12 teams on October 7 and 8 to detect what might have gone wrong and test a new tire to be used for the 2009 race. A total of 7 tests were conducted in preparation for the 2009 race.
The results of these tests indicated an increased amount of load and slip on the right rear tire caused the particle debris to be smaller than anticipated. This prevented rubber from adhering to the track and prevented tire wear from improving as the race progressed.
