I didn't realize this post was being taken so seriously. So here's my corrections to this. Apologies to Tasdrouille for not adressing this earlier.

RR is only 29% greater at 100 mph as it is at 35 mph for tires without cap plies - and only 13% greater for tires with cap plies.

The relationship between inflation pressure and rolling resistance is a decreasing curve (as the inflation pressure increases). The difference between 40 and 48 psi is only 2%.

A tire's ability to absorb an impact decreases 20% as the inflation pressure increases from 32 psi and 40 psi.
