In the course of testing the handling of a car, use tire temperatures
and driver feel to make adjustments. It is critical to monitor tire temperatures often.
They offer valuable clues to the setup of the car. The areas of adjustment that
tire temperatures are used for include: tire pressure, camber, body roll,
shock settings, wheel width and transient handling response.
Troubleshooting Tire Temperatures |
| Reading | Handling problem | Reason |

|
Compound too soft for track and ambient temperature conditions. |
| Front tires too hot |
Understeer |
Front tire pressures too low. |
| Rear tires too hot |
Oversteer |
Rear tire pressures too low. |
| Inside edges too hot |
Too much body roll |
Too much negative camber or too much toe-out. |
| Outside edges too hot |
Too much body roll |
Too little negative camber, too little toe-out or too much toe-in or wheel width too narrow for tire width. |
| Center of tread too hot |
|
Tire pressure too high. |
| Edges on too hot |
|
Tire pressure too low. |
| All tires too cold |
|
Compound too hard for track and ambient temperature conditions or car not being driven to limit. |
