That 32psi you set in your garage is actually 38psi by turn three. Most autocrossers lose seconds because they don't account for heat buildup. Your tires gain 6-8psi from cold to hot, completely changing contact patch and grip levels mid-run. → Physics: air expands ~2% per 10°F increase → Problem: overinflated tires = smaller contact patch = less grip → Reality: what feels good cold feels like hockey pucks hot → Solution: start 4-6psi UNDER your target pressure Save this before your next autocross - proper pressure management is the cheapest way to drop tenths. #ThreePieceUS #Autocross #TirePressure #SCCA #AutoX #TireSetup #Motorsports #TrackDay #TireTech #PerformanceDriving
