Don't discount the possibility that the tire guys may have bent a wheel or that the wheels or tires are out of round. It's not hard to bend a wheel on a tire machine if the tire guy screws up. You might jack up the truck, spin the tires and measure the lateral and radial runout. You can do this at home visually (look for wobble) but that's not conclusive. It's better to put a runout gauge on them and measure it. A well equipped tire shop should be able to do that. Often radial runout that is out of spec can be "fixed" by deflating the tire, rotating it 180 degrees, and rebalancing. Toyota should have max runout specs listed somewhere, I'm not sure where they'd find them. My guess is something like 15-20 thousands max but it's been a long time since my tire store days.

[edit] After sleeping on it I think the maximum allowable radial runout is more like 50 thousandths. Lateral runout is less.
