Tire Degradation
Calculation Mode
Choose between simulation-based or real-world temperature-based degradation modeling.
Tire Degradation (Simulation)
D = n × r × tf × sf
Where: D = degradation % n = lap count r = degradation rate (%/lap) tf = temperature factor sf = driving style factor

Tire Compound Characteristics
Typical Degradation Rates:
- • Soft Compounds: 1.5-3.0% per lap
- • Medium Compounds: 0.8-1.5% per lap
- • Hard Compounds: 0.3-0.8% per lap
- • Wet Tires: 2.0-4.0% per lap
- • Endurance Tires: 0.2-0.5% per lap
Softer compounds provide more grip but degrade faster.
Understanding Tire Degradation
Tire degradation is the progressive loss of grip and performance due to wear, temperature cycles, and chemical changes. Managing degradation is crucial for optimal lap times and race strategy.
Benefits:
- • Predict optimal pit stop windows
- • Maximize tire performance across a stint
- • Adjust driving style to manage tire life
- • Plan compound strategy for race distance
- • Gain competitive advantage through tire management
Key Considerations:
- • Overheating accelerates degradation significantly
- • Understeer/oversteer increases edge wear asymmetrically
- • Safety car periods can help reset tire temperatures
- • Fuel load affects grip and thus degradation rate
- • Real-world data always trumps theoretical models
