You have started out with the assumption that these higher efficiency tires are worse gripping. However, the article states that the manufacturer-supplied tires are generally more efficient (in order to get the milage numbers they advertise), and that it is the third-party replacements that are worse.
So either the manufacturer-supplied originals are more dangerous than replacement tires, or your argument is missing something.
The rest of your quasi-questions all would need to be evaluated to see if they are true or not... and one would hope that at least some of them were evaluated when creating the policy. You seem to be assuming they were not, without any real evidence one way or the other.
