IndyCar Returns to Phoenix for Tire Testing Ahead of 2023 Race Weekend
Phoenix, AZ – Scott Dixon and Alexander Rossi participated in a crucial tire testing session at Phoenix Raceway on Thursday, marking IndyCar’s first on-track activity at the oval since 2018. The two-day test aims to assist Firestone in evaluating various tire options for the upcoming race weekend on March 6-7, where IndyCar will share the track with NASCAR.
“It’s good to be back doing a proper tire test,” Dixon stated. “We’ve got compounds, constructions, and tire widths. This effort reflects Firestone’s commitment as a true partner in enhancing performance and safety.”
The Dallara DW12, utilized by IndyCar, has undergone significant changes since the last race at Phoenix, gaining upwards of 150 pounds due to the addition of the aeroscreen and energy recovery systems. This increased weight necessitates careful consideration in tire development.
To mitigate peak power and speed, Dixon’s and Rossi’s cars are testing at low turbocharger boost settings. This strategy is designed to reduce tire stress while accommodating the heavier cars’ high downforce requirements. Dixon noted, “The configuration is significantly heavier, influencing tire management throughout the session.”
Referring to the recent NASCAR race at Phoenix, where multiple tire failures impacted championship outcomes, Dixon emphasized the importance of the tire test for enhancing race conditions. “Our focus is on improving racing rather than pure performance,” he added. “It’s critical to address these changes to make racing better across various circuits.”
Times from Thursday’s testing sessions reflected the new parameters, with Dixon posting a morning time of 21.233 seconds and an afternoon best of 21.092 seconds. Rossi closely followed, showing competitive performance with times of 21.441 seconds and 21.107 seconds respectively. These times contrast sharply with the pole position of 19.5 seconds (188.5 mph) established by Sebastien Bourdais in 2018.
Dixon anticipates that fan reactions will highlight the speed differential between IndyCar and NASCAR, as qualifying times are expected to average around 20.5 seconds, significantly faster than NASCAR’s last pole of 133.7 mph. “They will be amazed at how fast we are compared to other series,” he concluded.
As the tire testing continues, IndyCar seeks to ensure optimal performance and safety standards ahead of its much-anticipated return to Phoenix.
