I've got it all sorted now, here was the breakdown:
I took it to the Goodyear installer on East 2nd St in Oswego, where they did an alignment and adjusted the toe angle. That helped the drift, but at 55 + mph I got a great deal of vibration from floor to steering wheel. I went back yesterday when the spare I ordered came in and did a road test and re-balancing.
Turns out that the shop that installed the duratracs initially (not Goodyear) used an old technique of counterbalancing clip on weights that sort of masked a less than stellar balancing job. In addition, they'd moved a wheel to the back as a spare but didn't notice a wheel spacer was still attached, meaning out of four wheels on the ground only 3 were spaced correctly. And the shop lost a centering ring in the process.
Goodyear rebalanced everything, installed the duratrac tire on the spare, and noticed that rim was defective, something the previous shop hadn't caught. These were the Ultra Motorsports "Bolt" wheels in 17 x 8 I had put on in August.
So, for the tire mounted and balanced plus road hazard protection plans put me at $346. Considering the work that went into it and the fact that it runs great now I'm pretty happy. As for the defective rim, they're an authorized installer from Tire Rack so I should be able to get that one switched out no problem.
