Tire Rotation
 

Unfortuantely I've never had a set of tires on long enough to do a rotation until now. I'm getting a bit of steering shake around 45 mph and had it in 3 times to do a wheel balance for the two front tires. It's get's a little better each time but not perfect as when I first bought the wheels and tires. Each time they did it on their "Road Force" equipment and the wheels and tires roll perfect. However, I still have an annoying shake.

Again, they road perfect until I got the rotation. Should I have gotten all four wheels balanced again and not the just the front two? I had them check the wheels anf both the wheels and tires check out perfect. They are all under warranty so I don't see any issues.

Any thoughts?
