I also would like to address the questions from

at length today to get more details. He did leave out a little bit of info from his first post, which I'll add below followed by comments.

installed BFG KO2 tires on his Overlanders, but the tires came off of his original 17" Trail Edition OEM wheels. The tires have about 15,000 +/- miles on them, and he had to have them balanced / re-balanced five (5) times on the OEM wheels. Per
@
CC4R
, he always had some vibrations with his BFG KO2 tires on his OEM wheels, and the vibrations persisted (or possibly got worse) when he took them off and installed them on his new wheels.
In my 20-ish years experience in this industry, this is not an uncommon issue with the BFG KO (original) or now the BFG KO2 (new) tires. The KO2 tires are commonly out of round, and they can be difficult to impossible to balance on any set of wheels. They often require multiple attempts at balancing, and even then go out of round quickly and require re-balancing often. It wouldn't be unusual to take them off a set of wheels and install onto another, or even to do a tire rotation and then find that you picked up a vibration where you previously didn't have one (possibly because the tire was in the back and now it's in the front). Please don't take my word for it, there are many reviews from customers on BFGs website regarding balance and vibration issues (not just Toyota 4Runner or even Toyota truck owners either):

The problem seems to be manufacturing inconsistencies. When the tires are good, they are really good, but when they aren't, they are really bad. Based on my limited data from speaking to customers over the years and installing BFG KO / KO2 tires (when I offered installation services), I would say that 75%-80% of the tires have no issues, but 20%-25% will be difficult or impossible to balance. I have nothing against BFG as a company, and harbor no ill-will by stating these observations. I know from a manufacturing standpoint it is much easier to make a precision CNC machined aluminum wheel as close to perfectly round as possible rather than make an aggressive, multi layered, multi material tire perfectly round. With the BFG KO2 being one of the more aggressive all-terrain tires, it stands to reason that it's also going to be harder to make them true/consistently round. All of our wheels are checked and verified at multiple points with precise Mitutoyo instruments to ensure quality and consistency.
Regarding the separate issue of the lug nut question from
@
CC4R
- this is an issue that has come up with Discount Tire (America's Tire in California) stores in the last year or so. I know that the issue stems from one (or maybe more, but at least one) of their stores installing wheels for a customer who had inexpensive, over the stud type wheel spacers (not the billet wheel adapter with built-in studs type, but the type that slides over the original studs and reduces stud engagement). They had a customer (or customers) who lost wheels on the road as a result of their installation of the wheels with these types of wheel spacers.
As a result they've instituted an ever changing, often misinterpreted corporate policy within their stores. We've explained and proven the engineering behind the stud engagement with our wheels and the lug nuts we provide. I've also personally shown our data alongside Toyota OE wheel measurements to Discount Tire indicating that our wheels engage the same amount of stud as certain OEM Toyota TRD wheels that use the same style (conical seat) lug nuts on the same 12mm diameter / 21.5mm length studs. Stated more simply, this means that Toyota engineers also agree with the data regarding stud engagement with this type wheel, lug nut and stud combination.
We have tens of thousands of customers (myself included as I own three Toyota trucks all equipped with FN Wheels) driving thousands and thousands of miles on our wheels every year. Safety and quality are our number one concern. We've never had any safety issues with our wheels and/or lug nuts, because there aren't any issues. All of the engineering data for our Toyota truck wheels is tested and verified before we ever sell a wheel to a customer. This includes properly machining and drilling for maximum stud engagement on Toyota trucks (including the short front studs) without compromising the integrity of the wheel itself.
It's important to use only the lug nut hardware that we provide, as the hardware has been properly selected to be used with our wheels. If you choose to use a different lug nut, it is important to check with us first, to ensure compatibility (just as you would when changing out any other parts on your vehicle). Our wheels are machined as deeply as possible to maximize stud engagement, and in the case of the Overlander and certain other models of our wheels where applicable, we also drill the wheels with lug openings just slightly larger than the diameter of your Toyota OEM 12mm studs. This ensures a snug fit over the studs and maximizes torque retention on the studs themselves (in addition to the wheels themselves being machined as deeply as possible in the lug area to maximize length of engagement).
I always feel like the proof is in the pudding, and one of our great customers has put his FN Wheels Overlanders thru tens of thousands of VERY hard miles and photo documented almost all of the miles here:
