runout is basically how perfectlly round your tire/rim is. it is funny you say sears....the tire balancer guys there really are the newest of the new for the mechanics. tech 1 opening position. but anyway...you could ask to see the runout. when the spin the wheel on the balancer they can shut off the machine and then open the hood of the balancer. this causes the wheel to spin freely. take something...anything that is stationary and hold it as close to your rim lip as possible.......now hold that same item close to your tire.

every tire has runout though...i would have him balance it again and tell the customer service associate that you would like to see if the rim is bent bc you still have the same problem.
