Reply to "Airless ti(y)res"

I would definitely suggest that just because there is no "pressure" change in a solid tire due to ambient temperature change, it does not mean there would be no change in effective radius, i.e., cal constant due to changing ambient temperature. Tire pressure is not the only thing that changes with changing ambient temperature.

All evidence I have, and I believe all Mike has, regarding differences due to changing rubber properties is anecdotal. But Pete Riegel did have some actual data. Many years ago Pete posted a graph he created from hundreds of pre-cal rides he did over the years. Pete always pumped his tire up to 100psi before doing his pre-cal rides. So if changing tire pressure was the only thing that mattered when the temperature changed, then all of his pre-cal rides in different temperatures should have given the same cal constant (since the pressure was always the same). But they didn't. Something else changed with changing temperature that affected his cal constants.

I'll try to find that post Pete made with his cal ride data.
