IndyCar Teams Navigate New Tire Strategy for 2026 Season
Several IndyCar teams are preparing for the 2026 NTT IndyCar Series season opener at St. Petersburg with uncertainty surrounding a new tire strategy implemented for all street courses. The updated rule, introduced earlier this week, requires drivers to utilize one set of primary (hard) tires and two sets of alternate (soft) tires during the race, a change from the previous requirement of one set of each compound.1 The rule regarding a minimum of two green-flag laps on each set remains unchanged.
Impact on Race Strategy
The shift in tire allocation has prompted drivers to assess how the new strategy will affect race performance. Christian Lundgaard, driver for Arrow McLaren’s No. 7 Chevrolet, emphasized the importance of tire durability. “I think it all depends on the tire,” Lundgaard stated. “Is the tire good enough? Is it better than last year? I think that’s what we all hope. Is it going to be a three-stop probably? Is it going to be a three-stop flat-out? Maybe not, depending on how the tire hangs on.”1 He also anticipates varying strategies depending on the track, noting that shorter circuits like Detroit and Washington D.C. May see significantly different approaches compared to St. Petersburg.
Firestone’s New ENLITEN Technology
Adding to the complexity, Firestone has introduced its new ENLITEN Technology into the Firehawk race tires.1 This technology replaces natural rubber derived from guayule, previously used since 2023, with renewable soybean oil, recycled steel, and recycled black carbon.
Driver Perspectives on Tire Performance
Alexander Rossi, driving the No. 20 ECR Chevrolet, highlighted the uncertainty surrounding the performance of the new alternate tire. “It’s supposed to be longer lasting than last year. How much longer lasting? That’s going to determine where you’re going with that question,” Rossi explained.1
Kyffin Simpson of Chip Ganassi Racing acknowledged the demand for on-track testing to evaluate the new tires. “Every year there is a new tire, so we will see what the new tire is like this year,” Simpson said. “If the alternative compound is strong enough that I can do 30 laps in a row without a problem, then it will be great, but ultimately I think that whenever you impose tire choices like that, you limit the strategic options a little bit.”1 He suggested the new rules could lead to unpredictable race scenarios, similar to the tire degradation challenges experienced in the previous year’s St. Petersburg race.
Technical Regulations at St. Petersburg
In addition to the tire strategy, teams are also managing hybrid deployment regulations. They are allowed a total of 150 seconds of hybrid deployment, capped at 15 seconds per activation, with a maximum of 310 kJ per lap. INDY NXT cars have a total of 50 seconds.3
The Firestone Grand Prix of St. Petersburg is scheduled to take place from February 27 to March 1, 2026.3
