Whakaotihia te rerenga e whai ake nei: Ko te wa o te AAA Championship Car 1955 e 11 nga whakataetae, i timata i Speedway, Indiana i te Mei 30 ka mutu i Phoenix, Arizona i te Noema 6. I reira ano hoki tetahi kaupapa kore-tohu i Mechanicsburg, Pennsylvania. Ko te AAA National Champion me te toa o Indianapolis 500 ko Bob Sweikert. I patua a Manny Ayulo i Indianapolis i a ia e whakangungu ana mō te
1955 Indianapolis 500, a ko Bill Vukovich, te toa e rua-wā, i mate i te whakataetae. Ko Jack McGrath, te toa toa e rua (1952, 1953), i mate i te whakataetae whakamutunga i Phoenix i te huringa 85. Koinei te tau whakamutunga o te AAA National Championship; I whakamanahia e te USAC te raupapa mai i te tau e whai ake nei.
