1998 Indy Racing League

The 1998 Pep Boys Indy Racing League was one of relative stability compared to the previous two seasons. For the first time the season consisted of a single and complete spring, summer, and fall like all other motorsports. 15 drivers completed the entire 11 race schedule, twice as many as the previous season. It was also the first complete season for the new Riley & Scott chassis, though it proved unpopular due to its late introduction. A. J. Foyt Enterprises drivers captured 4 wins, the Indy 500 pole, and the championship, arguably the most successful year in the team's history.

All races were run on oval speedways.

The eight races that were held in calendar year 1997 returned in 1998, with the addition of three new races. As part of their effort to venture in traditional stock-car markets, the IRL held the second Indy-car race ever, the first since 1969, at Dover International Speedway, and also competed at the reconfigured Atlanta Motor Speedway, which had been raced eight times by Indy-cars in its former shape between 1965 and 1983. A second race at Texas Motor Speedway in the fall completed the calendar.

The Indy 200 was held on January 24 at Walt Disney World Speedway. Qualifying was rained out, so Tony Stewart won the pole position due to the race being lined up by 1996–97 entrant standings for the first 20 positions and the remaining eight came from the best practice speeds of the remaining cars.
