Rahal-Letterman Racing signed Meira to a three-year contract in 2005, with backing from longtime supporter, Johns Manville and Menards. One notable race finish during the year was a second place to Dan Wheldon at the Indianapolis 500. Meira gave Rahal-Letterman Racing their best final point standing finish of seventh as well as recording seven top five and eleven top ten finishes for the team. After losing a majority of the funds for the #17 car, Rahal-Letterman needed a driver who had sponsorship with them. For Meira, that meant losing his ride to Paul Dana, who brought Ethanol sponsorship.
