Rear wheel wobble, what can be done?

[SummerallGuard04]

I recently noticed that one of my rear tires wobble slightly. Nothing major, but when I get to speeds in excess of 70 MPH, I'm pretty sure I can tell a difference in the ride. It's definitely the RIM and only the rim because I swapped sides with the other side to confirm. Planning on taking it to a wheel specialist--think it's a waste of time/$$? I have the 6 star Tundra Enkei steel 265/75/r16s (pics in my garage).

Thanks

could the balance weights have fallen off? That would cause a noticeable wobble. Unless you hit something hard with it and bent the rim.

you know its the rim, and not the tire how?

you can have the tire dismounted, and throw the rim on the balancer. you'll be able to tell right away.

uless you hit something with it, its not likely to have a wobble.
its much more likely its a tire.

If you haven't taken it in already you can jack up the suspect wheel and use some sort of hardened wire and point it at the rim of the wheel. Spin the wheel and see if the distance from the rim to the wire changes.

Are you sure those are steel? They look like aluminum in the pictures.
