Tire Temperature - What is Significant?
I got an IR thermometer "gun" and started using it on this trip for the first time. I'm not sure what I'm looking for. After an hour of 60mph driving in 70 degree F temperature, I pulled off the roa...

My tire temp info comes from a lot of road racing and open lapping events on road courses. These folks put a lot of faith in the follow methods.
Your temp guage need not be state of the art just accurate between measurements if it is always off 5 degrees it will work just fine fine. It just can't be off 5 degrees in the same spot moment to moment.
The method I use is simple and can be used anytime after the tires have been run for a while.
Pick any tire and use the temp gun on the outside, center, and inside of the tire face. Make sure you temp the same distance from the outside/inside of the tire and the exact center. If you measure tread face do so on all three measurements. If you measure the groove do so on all three measurements.
Here is the benefit and what you can learn.
100-110-100, Your tire is over inflated as the center temp. Is higher indicating higher friction
110-100-110 This tire is under inflated
(more friction on the outside).
Remember the point here is not the temp it is the temp difference between outside and inside.
