As stated above, the Hunter 9700 is what should be used. Even though Toyota wheels are hub centric, using the Haweka adapter or finger plates will give the 4Runner wheels a much better balance. I went through six rebalances and a road force on my old Tacoma with BFG KOs before suggesting the Haweka. Solved the issue.
If you are dealing with a very good tire technician, it shouldn't matter. And yes, there are defective tires, but if you are having issues on more than one I'd lean towards poor install.
You can search for shops that carry the Hunter 9700 on the Hunter website here:

I would not recommend having tires balanced at a shop that does not carry the 9700.
