The downside here is that you have to buy a new device and learn to use it, but it will provide very accurate info. I'l admit that I have not gone to this level. Yet.

I have got one of the budget pyrometers, but I like it because it has a right-angle tip and I can configure the depth of the probe.

What I am missing is some crew to check it for me if I come in to the hot pits in the middle of a session.
And on a PCA DE where you only get 20 minute sessions, you lose 1-2 laps coming in. I guess I could come in hot right at the end of the session and not lose any time that way, and then drive around the paddock to get a cool down.
I have used it a couple of times after the session was over and I was back in the paddock, but I figure that the tire has cooled down so much by that point I'm not getting accurate "hot" temps. The few times I have done it, the temps were all even although the left tires were hotter than the rights. I will have to dig out my sheets and see what they said... I just remember it was pretty even.
Anybody that comes to the same DE I am at, if we are in different sessions, I would be happy to check your temps and pressures if you want to come in to the hot pits in your session.
Or if we are in the same session you can borrow it and check them after.
