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.
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.
Cheever became the first owner/driver to win the Indianapolis 500 since A. J. Foyt in 1977.
Cheever, whose team was unsponsored prior to this race, planned to shut down his team after the race. However, he and teammate Robby Unser received sponsorship from Rachel's Gourmet Potato Chips. This, combined with Cheever's victory, kept the team open the rest of the season.
Because St. James failed to qualify, the starting lineup consisted of only men for the first time since 1991.
On the first lap, Yeley spun out and collected Cheever. Both recovered to finish in the top 10.
Bräck ran out of fuel while leading. As a result, owner Foyt threw the laptop computer that said that Bräck had enough fuel in anger.
Boat's only IndyCar win. He had been declared the winner at Texas the previous year, but a scoring error was discovered that resulted in Arie Luyendyk getting the win.
Boat was involved in a large crash lap 95 and missed the next two races.
Team owner John Menard Jr. believed that A. J. Foyt Enterprises was cheating and withdrew his car driven by Robbie Buhl from the next two races. His other car, driven by Stewart, was not withdrawn as it was leading the point standings.
Luyendyk's final IndyCar win. It would also be his final season as a full-time driver, as he would choose to go into semi-retirement in 1999.
Of the championship contenders, Tony Stewart started 2nd, but spun on lap seven and finished 14th (30 laps down), Davey Hamilton was involved in a crash with Roberto Guerrero on lap 130, finishing 19th. Bräck cruised the rest of the way to finish 10th, six laps down, enough to win the championship.
Any driver who qualifies but does not start (DNS), earns all the points had they taken part.

Ties in points broken by number of wins, followed by number of 2nds, 3rds, etc., and then by number of pole positions, followed by number of times qualified 2nd, etc.
Additional points were awarded to the pole winner (3 points), the second best qualifier (2 points), the third best qualifier (1 point) and to the driver leading the most laps (2 point).
Notes: Orlando: No additional points for the qualifying were awarded due to rain; starting grid were determined by 1996–97 entrant points for the first 20 positions and the remaining eight went to top practice times from Thursday. Phoenix: Scott Sharp had 7 points deduction, because his car failed the post-race fuel capacity inspection. Pikes Peak: Tony Stewart and Robbie Buhl had 15 points deduction each, because the rear wings of both Team Menard cars were found to be in violation of technical specifications.
