I've been reading a report suggesting higher tread wear ratings corresponds to higher rolling resistance, but only in passing. Does anyone else have any source material on this?

Evidently ~5% of vehicles have ratings between 600 and 800 (the highest grouping), and my former tires were 680, so if this were true that might explain my big MPG jump with the switch the LRRs.

Thoughts?
