Rolling resistance of tires?

Hard to say what Cessna's assumptions are, especially when they didn't
include their formula, just a data set.

I would think rolling resistance would be less at lower temperatures.
rubber softens at higher temps and gets a better grip. the data shows
the reverse , at lower temps for the same density altitude the
distance required is higher.
