No, Troy. Tires with high treadwear numbers give poor RR - they generate lots of hysteresis.
The triange is treadwear, traction, rolling resistance. These 3 properties are balance in a tread compound and gains in one must result in sacrifices in one or more of the others. So as a general rule tires with good rolling resistance (such as OE tires) generally have poor treadwear or traction (or both.)
