Delta - Tyre Strategist

Delta Tyre Strategist analyses how race tyres degrade and predicts lap times as the race progresses. Pick a round, see how the strategy plays out, then try your own and see if you can beat the model. Built for motorsport fans who want to think like a race engineer on the pit wall. TYRE DEGRADATION ANALYSIS Every compound nominated for each round of the 2026 calendar, from hardest to softest How much pace each tyre loses per lap, when it falls off the cliff and how long it takes to warm up Track temperature changes how fast the tyres wear, and the predictions follow Circuit maps coloured by tyre load, with the corners that punish the tyres most and the wheel that suffers most LAP-TIME PREDICTIONS AS THE RACE PROGRESSES Predicted lap time for every lap, including fuel burn, tyre age and pit stops Play the race lap by lap, or watch it as a timelapse at 1×, 2× or 4× Touch and hold the lap chart to read any lap See the gap to the next-best plan lap after lap TRY YOUR STRATEGIES Delta works out the fastest plan for each round, from one-stop to multi-stop, with its pit window Build your own plan: pick each stint's tyre and the lap you box, and see how much time it gains or loses against the model's plan Respects the two-compound rule in dry races WHEN THINGS CHANGE Rain coming? Set when it starts and how long it lasts, and the plan switches to intermediates or wets Replan mid-race from the current lap, the tyre on the car and its age Safety car and virtual safety car make a pit stop cheaper, and the plan adapts CHECK THE MODEL AGAINST A REAL RACE Tap once to download the last race at that circuit from the public openf1.org timing data Compare real lap times with the predictions, then apply the fitted pace and wear to your own plans No account, no ads, no tracking.
