The neverending saga continues. The vibrations persist, so the manager took it out for a spin himself. He says that he felt shaking in the front and rear. He thinks that the TRD Pro wheels may not be compatible because of the difference in rim width (going from 7.5" wide steelie to 7" TRD Pro), and the difference in offset. He says that changing out the wheels pinched the tires in, and also effectively decreased my track width, which is causing loss of overall stability.
Can someone verify the info about the track width? I was under the assumption, after much reading, that the TRD Pro wheels would increase my track width by half an inch on both sides, for 1" overall?
They're now swapping out the fronts one more time. Worst case scenario, I'll have to put my old steelies back on with the Wildpeaks, I think. I'm super disappointed that this is happening, especially that these aren't oddball rims. They're pretty popular for FJs. Sigh.
