individual wheel rolling resistance test

Lately i have been trying to find some lrr tires and that got me thinking why don't i check out the resistance of each wheel to see if maybe i have a bearing that's about to go bad and fix that while I'm at it. Never doing this before I thought id run my hypothesis past you guys. Which idea do you like better.
1. Jacking the car up tires off the ground tranny in neutral.
use a torque wrench to check the force required to turn the wheel and compare to the other side (front and rear will be different because of cv shaft
2. Create a jig to set one tire on at a time. Using electric motor bring the wheel speed to set point and disconnect power and time the wheels movement till it halts

Ones really easy but the other would test it under normal load. Ideas guys?
P.s. I work on convayers all day a jig would only take 3-4 hours to build with parts already on hand
