Timing & Strategy

Tire Degradation

Model tire wear impact on lap time over a stint.

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

Lap Count:

Degradation Rate (% per lap):

Track Temperature (°C):

Driving Style Factor (0.8-1.2):

About this tool

The BuildLockr tire degradation calculator estimates the rate of tire wear during track sessions. Use this tool to calculate grip loss, heat cycle effects, and performance drop-off over consecutive laps. Whether you are setting up an endurance race strategy or optimizing tire pressures for track days, this tire wear estimator provides critical guidance. This helps racing drivers manage their tires, optimize stint lengths, and maximize traction throughout a race event.

Understanding Race Tire Wear and Grip Loss

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.

Common Tire Degradation Questions

What factors cause the fastest tire degradation?

Overheating, improper alignment (toe/camber), aggressive sliding, rough track surfaces, and heavy vehicle weight.

How do you identify tire heat cycling?

Heat cycled tires become hard and lose grip even if they have tread depth remaining, often showing a blueish tint on the tread surface.

How can you reduce tire wear on track?

Smooth driving inputs, correct tire pressure settings, proper suspension alignment, and taking cool-down laps.
