That's great stuff Bob. Thanks for posting the links.
In the temperature sensitivity study it was determined that pumping a tire up to its maximum pressure, or leaving it at a lower pressure, did not change its temperature sensitivity.
But I don't think it answered the question of whether a tire with a lower pressure rating would have more temperature sensitivity than a tire with a higher pressure rating. For mountain bikes anyway, a lower pressure rating usually means a fatter tire, so their tire width effect would be there. But I have two wheels at home with tires of the same width but significantly different pressure ratings. I'll have to give this a test.
