The Vols agreed last year to play Virginia Tech on Sept. 10, 2016, in a game that could be one of the highest attended sporting events in American history.
Both schools were allotted 40,000 tickets for the game. UT said the school had taken deposits for 35,000 of the tickets; the remaining 5,000 would be reserved for students.
UT said it planned to ask the speedway for more tickets to the event.
The capacity of the racetrack when configured for football could be in the range of 150,000.
