tire temp info

I bought a infa-red guage at radio shack & wrote to Goodyear for tire temps,
here is there

Mr Smalley -

Sorry for the delay in getting back with you.

Tire temperatures reflect many variables: Ambient temp, road surface temp,
ventilation,
tire construction, tire type, tire loading,
inflation pressure, speed, brake heat, etc.

Tire manufacturers are more concerned about a tires internal temperature, with
two
hotspots being the tires shoulder (thickest part of
the tire) and the tires bead area (area that contacts the rim).

Relative to your question a nominal surface temperature of 150 deg F would not
be
uncommon. Anything over 185 deg F would be abnormal
and would raise a flag relative to 'cause' of the elevated temperature.

Getting a relative feel for the tires temperature is not a bad idea, however to
accurately
determine the temperature would require an
infra-red temperature sensing device or something similar.

Thanks for the question.

Best regards!!
