No Lift tire size guide (work in progress)
I just pulled the plug and ordered 275/55/20 Cooper Discoverer Road+Trail AT tires on Black Rhino Alston +25 offset wheels. I will post pics once installed. I really hope they don't look too small, though I do think they are the best size for the space provided.
However, the MSPN (Michelin product number) is 20879 according to the PDF. They did confirm the OEM 20" size will be available in August, so assuming the 19" is still on the table, I'd assume it'd be in August, too. Still awaiting to hear back from BFG if they did in fact decide not to make the 19" size.

I finally found a goid copy. I had that PDF before but I switched phones recently. 20879 is what I remembered. That sure makes it look like it's coming.
If you're referencing the OEM sizes for the KO3, they aren't available yet. The 20" will be available in August, and the 19" are confirmed for sometime this year. When they will be available, you can order them from your local tire shop or places like Tire Rack or Costco etc.
My new D130 400 came with 22 inch wheels. My LR4 has 20 inch with Nitto Ridge Grappler 285/50/R20, prior Johnson Rod lift, now springs with very slight rubbing. Specs are 31.26” diameter, 11.69” width. Daughter getting LR4 for street use, can I switch wheels between trucks?
No rub at standard height would be great, although I have a 1 inch lift programmed on D130.
