Tech Section: Intermediate Aero & Goodyear Spec
Las Vegas utilizes the 2026 Intermediate Package, featuring an unrestricted 750 Horsepower engine and full downforce aero (larger spoiler and full diffuser strakes) [9, 10].
Goodyear Racing Eagle Specs: This setup (Left: D-5284, Right: D-5290) was previously run at Las Vegas and Kansas in late 2025 [11].
Heat Management: These tires are specifically designed to shed rubber [12]. This process allows heat to dissipate through the tread, keeping the carcass cooler and promoting predictable fall-off over a 50-60 lap run [12].
Min Inflation: LF: 20 psi | RF: 50 psi | LR: 22 psi | RR: 46 psi [13].
