yep, likely a wheel speed sensor issue.

but i would walk around and verify that they gave you 4 of the same size tires, because if you only did 2 tires, or they messed up the sizing on one, it would cause a similar issue.

when you had the alignment done, did they give you a print-out of the before and after specs?

if the alignment was significantly altered, that could also affect it. especially in the steering, as there's a steering angle sensor that must also be recalibrated if significant changes are made.
