1991 Pyroil 500

[1][2][3] To fill out the top three, owner-driver Darrell Waltrip and Junior Johnson & Associates driver Sterling Marlin would finish second and third, respectively.

[4][5] Phoenix International Raceway – also known as PIR – is a one-mile, low-banked tri-oval race track located in Avondale, Arizona.

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.

For this specific race, positions 21-40 would be decided on time,[6] and depending on who needed it, a select amount of positions were given to cars who had not otherwise qualified but were high enough in owner's points; which was one for cars in the NASCAR Winston Cup Series and two extra provisionals for the NASCAR Winston West Series.

Geoff Bodine, driving for Junior Johnson & Associates, would win the pole, setting a time of 28.220 and an average speed of 127.569 miles per hour (205.302 km/h) in the first round.
