                             Tire Temperature Testing

Tire temperatures and proper tire inflation are often overlooked in the overall performance
of your vehicle.  Tire temperatures can give you an idea of whether your camber is too far
negative, there's too much body roll in the vehicles chassis, and can help pinpoint issues
with oversteer and understeer.  The following chart is from a SCCA setup guide.  To help
test your tire temperatures and track your progress as you tune, I have supplied the
following
chart that you can print out.
Troubleshooting Tire Temperatures
Reading
Handling
Problem
Potential Cause
All tires too
hot
  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, too much toe out, spring
rates, roll bar size.
Outside
edges too
hot
Too much body
roll
Too little negative camber, too little toe out or too much
toe in, spring rates, roll bar size, or wheel width too
narrow for tire width.
Center of
tread too
hot
  Tire pressure is too high, or rim is too narrow for the tire.
Edges on
tire too hot
  Tire pressure is too low, or rim is too wide for the tire.
All tires too
cold
  Compound too hard for track and ambient temperature
conditions or car is not being driven to the limit.
Front tires
too cold
  Inadequate load on front tires.
Rear tires
too cold
  Inadequate load on rear tires.
