This is a good tool when your car is fast and needs fine tuning. Tire temperatures are of little value when your car is not handling. If your car is handling poorly, the front tires will slide early on entrance to the turn and the rear tires will slide on exit. The sliding overheats the tires and can make the temperature sheet look balanced.

Temperature readings are more valuable as you get faster and faster. You can use the temperatures to assist you in fine-tuning the chassis. You might see something in the numbers that lets you look into the future allowing you to make a fine adjustment that improves the handling of the car on a long run.
 
It is generally best to run a minimum of 10 laps before you check temps.  Otherwise, your setup may run for a few laps then wear out fast.
 
Make one adjustment at a time!  If you want to change a few things, write them down and adjust them individually.
 
If your car has a tendency to push, try slowing down (ie. roll off the gas into the turn; stop using your brake) because trying to be fast during practice can mess up your tire loads and temps. Remember, you have the ability to practice to make sure your car is set up to run consistent before a race, so make sure your car is going to last by not exactly trying to get your fastest lap time every lap.  This is probably the most common mistake made.  When you learn this, you will actually go faster!  That's called seat time and experience.
 
I can mostly trust iRacing's default setups as a "ball park" set for each track. The closer you get to your optimum setup, the more value your temps will provide to use within this tool.
 
As always, driver error can skew the tire temperature averages.  Driving the track incorrectly may result in setting up your car for a driving style that will cause wrecks and might even provide you with wrong setup adjustment recommendations all around.  Different cars can have different lines on the same track, so it can be a great benefit to study the good guys and their lines during practice sessions.
