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

For this specific race, positions 21-40 would be decided on time,[7] 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.

Rusty Wallace, driving for Penske Racing South, would win the pole, setting a time of 28.094 and an average speed of 128.141 miles per hour (206.223 km/h) in the first round.
