Background
Phoenix International Raceway – also known as PIR – is a one-mile, low-banked tri-oval race track located in Avondale, Arizona. It is named after the nearby metropolitan area of Phoenix. The motorsport track opened in 1964 and currently hosts two NASCAR race weekends annually. PIR has also hosted the IndyCar Series, CART, USAC and the Rolex Sports Car Series. The raceway is currently owned and operated by International Speedway Corporation.

The raceway was originally constructed with a 2.5 mi (4.0 km) road course that ran both inside and outside of the main tri-oval. In 1991 the track was reconfigured with the current 1.51 mi (2.43 km) interior layout. PIR has an estimated grandstand seating capacity of around 67,000. Lights were installed around the track in 2004 following the addition of a second annual NASCAR race weekend.

During the first round, the top 25 drivers in the round would be guaranteed a starting spot in the race. If a driver was not able to guarantee a spot in the first round, they had the option to scrub their time from the first round and try and run a faster lap time in a second round qualifying run, held on Saturday, November 6, at 10:45 AM MST. As with the first round, each driver would have one lap to set a time. Positions 26-36 would be decided on time, while positions 37-43 would be based on provisionals. Six spots are awarded by the use of provisionals based on owner's points. The seventh is awarded to a past champion who has not otherwise qualified for the race. If no past champion needs the provisional, the next team in the owner points will be awarded a provisional.

John Andretti, driving for Petty Enterprises, would win the pole, setting a time of 27.126 and an average speed of 132.714 mph.

Mike Wallace was the only driver to fail to qualify.
