🏎️ Track Thermal Loading Characteristic
Tilke-designed circuit featuring Spa-Francorchamps Eau Rouge replica and Nürburgring Karussell banking. Strict 98dB sound limit monitored at T13.
🌧️ Wet Track Driving Line Notice
Exercise smooth inputs; painted curbing and pit exit lines hold standing water when damp.
🛰️ Live Circuit Doppler Weather Radar
Interactive animated radar loop centered over Atlanta Motorsports Park (AMP). Use the bottom scrubber to track approaching convective cells.
⚙️ Vehicle Setup & Compound Parameters
Configure chassis weight, tire compound, and desired hot operating pressure.
Examples: Bridgestone RE-71RS, Nankang CR-S, Yokohama A052, Falken RT660, Michelin Cup 2

⚠️ Chassis Cold Floor Protection Enforced (26 PSI): Calculated cold pressure fell below safe limits for Midweight (2,800 – 3,500 lbs). Starting lower risks tire carcass rollover, rim pinch flat, or shoulder delamination.
⏱️ The 60-Second Pit-In Rule: Hot tire pressures decay 1–2 PSI within minutes of leaving the track. Check hot pressures within 60 seconds of pulling into the pit box, then bleed excess to reach your exact target.
🌡️ Pyrometer Tire Temperature Diagnosis: Inside — Middle — Outside
How to read a probe tire pyrometer immediately after an HPDE session to distinguish pressure crowning from suspension camber alignment:
Ideal Track Camber Spread
Inside is 10°F to 15°F warmer than Outside
Shows healthy negative camber. The entire contact patch is utilized when the body rolls into high-speed apexes.
Over-Inflated (Tire Crowning)
Middle temp is > 4°F hotter than average of I and O
Tire center is bulging and bearing excess weight. Grip feels greasy. Action: Bleed 1.5 to 2.0 PSI hot.
Under-Inflated (Tire Dishing)
Middle temp is cooler than both Inside and Outside
Tire center is concave; load is concentrated on outer shoulders. Action: Add 1.5 to 2.0 PSI.
⚖️ Advisory & Legal Notice: Recommended tire starting pressures and meteorological compensations generated by this tool are educational approximations designed for closed-course driver education. Actual tire dynamics vary substantially based on vehicle curb weight, corner balancing, wheel rim width, static/dynamic camber and toe alignment, driver aggression, and tire manufacturer technical specifications. Always consult your tire manufacturer’s published minimum operating specifications.
🏎️ Session 1 Warmup Protocol: Never drop heavy street cars (BMW M, Mustang, Camaro) below 28–29 PSI cold before Session 1 in an attempt to reach an afternoon hot target. Cold radial tires on heavy platforms lack pneumatic sidewall stiffness before core heat builds; running excessively low cold pressures can cause catastrophic sidewall rollover, rim pinch flat, or shoulder delamination. Always stage your pressure drops over multiple sessions.
🚨 MANDATORY HIGHWAY RE-INFLATION WARNING: Tires bled down for optimal closed-circuit track grip will become dangerously under-inflated once cooled to ambient temperatures in the paddock. Drivers driving their vehicles home on public roads MUST re-inflate all tires to vehicle door jamb placard specifications using paddock compressed air before departing the speedway facility. Highway driving on track-bled cold tires risks catastrophic blowout, bead seal loss, and high-speed hydroplaning.
