Tire Pressure
Hi I have dual tires in the rear of my motor home & obviously 2 in the front I know front tires are to be set at 65 psi max & rear tires at 80 psi What is considered a safe range among all 4 rear ...

You are correct. I overstated the temperature spread. It is only 50F spread between the base of a groove and the outer tread surface. All you have to do is to be sure the entire area you are measuring is withing the "reading circle" when you use your IR gun. I sent you the link with the temperature data.
Very interesting article; lots of good info, and I am indeed surprised at the temp variation within a small area. However, that variation occurred between the tread surface and the bottom of the grooves; there was actually very little variation across like areas, ie the tire tread surface.
You make the point that a temperature needle probe, inserted down into the tire carcass to the cord is the only way to get an accurate temperature reading of the tire temp. Sorry, but I have no desire to stick anything into my tire multiple times. Perhaps that's not an issue on a race tire that will be removed and discarded at the next pit stop, but on my RV? Nope. An IR gun is, on the other hand, completely non-invasive.
Finally, the article spends alot of time debunking the idea that tire pressures can (or should) be set using an IR temp gun. Point taken, but neither I nor anyone in this thread has ever made the claim that tire pressures be set in that way. IR temp guns are, as I've said, simply an additional tool to (quickly and easily) look for a major variation that could indicate a problem, whether that is low pressure, failing bearing, dragging brakes, etc. Evidence that there MAY be a problem is the first step towards solving a problem.
Again, good article, but somewhat irrelevant to what I and others are actually using our guns for.
