Yes, correct.
I meant 17" and 16" previous gen BOF Toyotas have the bigger 106.1mm hub bore.
So technically New wheels will not fit old gens like previously.
Example : I have 2018' TrdOF taco wheels on my 99' 4runner.
The only thing I found is that most 17" wheels for Toyota 6x139.7mm have a hub bore size of 106.1mm, but the new 6th gen 4r (and 4th taco) have a 95.1mm so HUB rings are needed.
In Texas only a trade in will knock the value down you get taxed on. Cash won't have the same effect. That's why sometimes the tax saving might be better than selling a used car on the street vs trade-in (usually get less value than street). You just got to weigh the math and see what's better.
Lunar Rock is my favorite color. I was a bit sad it did not make it to the 6t gen.
Congrats on the 5th gen! I was considering one not to long ago TRD OR Lunar rock, but decided to wait for 6th.
