I just made it happen and figured this post could help someone else searching for the information!

Wheels are the 18"x8" Compomotive PD1881: See HERE
I have 265/60/18 BFG KO2 tires fitted
Running on the street 45psi for the front, 50psi for the rear
Factory TPMS fits and works
Factory center caps fit very loosely, so they're held in with some clear silicone
Unsprung mass (weight) should pretty close to the 21" factory wheels & tires (about 78lbs, unscientifically weighed on my home scale)
Suspension height is unchanged from factory, access height works as normal with these tires
Front wheels are static balanced as the tolerances are TIGHT and dynamic balancing caused the wheel weights to make contact with the bottom of the steering knuckle / lower control arm area.
Rear calipers ever so slightly etch the inside of the wheel.

I may have been able to fit a slightly wider tire. Maybe I'll try that next time.
Ride quality is noticeably better, which is to be expected when the sidewall doubles!
Purchased the wheels through Lucky 8: Lucky8LLC.com

Looks great! What is dynamic vs static wheel balancing?

Beautiful! I used to run these on my LR3 with 265/65/18. Did you look into 265/65/18?
How's the road noise vs. street tires?

Looks great. I was thinking of a similar set up but was informed by another member that certain engines wont work. IE, i have a 5.0 Supercharged with larger rotors and brakes. Please post up what your stock set up is so others can make an informed decision.

I would love a smaller wheel but it might not work 'out of the box' without swapping out the rotors and/or brakes.

Thanks! Dynamic gives better results but requires more weights. Here's a quick image explaination:

I didn't actually. I wanted as close to factory diameter as possible, at least initially. In my experience tire size #s are not very uniform across brands and this was my first BFG purchase. Turns out there a bit thinner than internet math would suggest.

Road noise is no worse than the worn set of Pirelli tires they've replaced. These vehicles are a bit more insulated from noise than most though.

Sorry, vehicle info is in my signature. In case others missed it this is a 2016 TD6. So yeah, this WON'T fit larger caliper models like the SC. I guess you could downgrade your calipers... but that doesn't seem worth it!
