Checking in on this thread in hopes this can help someone with more info.
I've not yet come to a solution, but hear me out. I think the shop I'm working with is on the right path and I will know more soon.
2019 ORP, TRD wheels. Kind coils in the front and Icon UCAs. Tires are 285 BFGs.
Shook a little brand new off the lot. Dealer said tires were never balanced. This solved the issue at the time.
Fast forward 20k miles and I get a lift and BFG KO2s. Slight shimmy, but Discount Tire fixed it. 5k miles later I go to rotate and it's a mess of a shimmy, so I go back and I'm told that one tire is asking for 15 oz of weight, so there's an issue. I swap it with an identical tire (my spare) and the shimmy is still there, but much less.
After a couple of attempts, they are trying using "smart weight" setting set to off on the Hunter machine, along with the Haweka plats. The interesting thing about "smart weight" setting, is that there are at least 2-3 reports I was able to found on the internet of Toyota using that exact procedure to get rid of the vibe issues on some Lexus 460 models. The tech told me that the total weight didn't really change doing this, but the position of them changed slightly.
Picking up the truck here in the next hour or so and we will see. I was able to be vibe-free for most of the 26k miles I've got on this truck, so I'm confident it's a tire/wheel issue.
Also, I did notice that weather affects the tires. If they sit a few days, they vibe a little until warm. Also when very cold out, they will vibe for a few miles and then smooth out. The vibe I'm referring to is the same one that many are dealing with, showing itself around 58-60 MPH or so.
