Keep in mind, those tests are done i a controlled environment.

In real world, you will have road and weather conditions that have a major effect on fuel economy...

A simple way to improve tire wear and fuel economy is keep your tires properly inflated.

Michelin tires are made by BF Goodrich...

IMHO, there is not a lot of difference between All-Season and All-Terrain.

All-season are generally associated with passenger cars where the AT are generally associated with light trucks.

Personally, I would go with the AT as they are a 3-ply sidewall.
