Tire Pyrometer Analysis
Enter the inner, middle, and outer temperatures of a tire to get instant alignment and pressure feedback.
Outside Edge
Center Tread
Inside Edge
Note: Inner temperatures are typically 10-20°F hotter than outer temperatures on a well-setup track car.
Heuristic-Based Guidance
This tool uses rule-based heuristics to suggest camber/pressure changes. These are not precise physics calculations—they're practical diagnostic guidelines based on common track car patterns.
Ideal temperature spreads vary by:
- Track surface temperature and grip
- Vehicle load and g-forces experienced
- Tire compound and wear state
- Car suspension geometry and setup
- Racing series regulations
Use as a diagnostic starting point, not absolute truth. Work with your tuner/team for final setup confirmation.
Analysis Thresholds
Camber Assessment:
• Spread > 40°: Excess negative camber
• Spread 20-40°: Decrease camber
• Spread < 0°: Increase negative camber
• Optimal: 10-20° inner hotter
Pressure Assessment:
• Middle > 7° above avg: Decrease pressure
• Middle < 7° below avg: Increase pressure
Measure immediately after cool-down. Tire temp drop ~1°F per minute after stopping.
Frequently Asked Questions
What temperature range is optimal for track tires?
Street tires peak at 80-120°C; racing slicks at 90-120°C. If center is 20°F+ hotter than edges, tire pressure is too high (overheating). If edges are hotter, pressure is too low.
Should I reread pyrometer data after the car is washed?
Wait 15-30 minutes after driving before reading. Tires cool quickly. Record data immediately after exiting the track while sensors are still warm for accuracy.
How do I know if I need alignment or different compounds?
Outer edge consistently hotter than the center = alignment issue (camber). Entire tire overheating = too much pressure or grip demand. Data guides your next suspension tuning decision.
