Curious that Kevin states the Nitto
Recon Grappler is a true 37" tire; whereas, the stock KO2 tires are less. It is well known that advertised DIA is slightly different than actual DIA; however, I fail to see the bragging rights for the Recon Grappler with only a
0.04" diameter gain. The video shows a noticeable unmounted and mounted diameter difference between the BFG and Nitto
(but that could be camera angle. Put the BFG in the back and Nitto in the forefront, then the BFG would look bigger for the same angle). I would be bragging more about the extra 2 plies and trail toughness. You could step up the BFG toughness to a D rating for an extra 7.25-lbs/tire at which point the BFG is the better tire judging by weight and tread depth (IMHO). I'm sure the spray for Nitto is due to sponsorship.
[Sidebar: kind of lame and unprofessional that the OEM tires were not balanced. Ford QC should have caught that and the Ford dealer should have caught that on pre-delivery inspection and test drive. Hmmm, what's causing this wobble? Maybe they didn't run it up to 80 mph like Kevin. However, I would expect better dealer service if I was paying $35k over MSRP for a truck. Curious Kevin didn’t turn-around and say something to the dealer when he first noticed it driving home instead of waiting to get on camera and badmouth Ford. I guess you don't care about those little things if you're in a hurry to be the first to drive a BRaptor off-road and spray about it. But I digress].
Stock: BFG KO2 37x12.5R17LT, 116S C BSW => 36.5", 63 Lbs, 6-ply, 15/32"
Upgrade 1: BFG KO2 37x12.5R17LT, 124R D BSW => 36.5", 71.3 Lbs, 8-ply, 15/32"
Upgrade 2: Nitto Recon Grappler 37x12.5R17LT, 124R D BSW => 36.54", 75.6 Lbs, 8-ply, 12.5/32"
Personally, I think the Nitto
Ridge Grappler tires are a better off-road choice if you were sold on Nitto tires; they are slightly bigger and have more tread depth for the same toughness, but are heavier (as expected).
Upgrade 3: Nitto Ridge Grappler 37x12.5R17LT, 124Q D BSW => 36.77", 81.5 Lbs, 8-ply, 18.3/32"
Bigger and tougher always means more weight. Rotational weight is more worrisome for suspension and steering component wear and tear than unsprung or dead weight. This should be a real concern for regular Broncos, but maybe not so much for the BRaptor. If you really wanted a bigger Nitto tire, then the 38" DIA Ridge Grappler tires might be the way to go; however, that would be almost a 19-lb/tire increase in weight for a 1.25" DIA gain. Kind of spendy IMO for no extra toughness (compared to stock), but it is another 5/8" increase in ground clearance. There might be a cost trade study in there somewhere. I can't see putting 39", 40" or 42" tires on my BRaptor.
Upgrade 4: Nitto Ridge Grappler 38x12.5R17LT, 118Q C BSW => 37.76", 81.9 Lbs, 6-ply, 18.3/32"
I've used BFG and Falken tires with good success off-road. I certainly like the Wildpeak A/T3W for the winter travel; however, they are heavier, but on the plus side they have a lot more tread. Compare to upgrade 1.
Upgrade 5: Falken Wildpeak A/T3W 37x12.5R17LT, 124R D BSW => 36.5", 82.5 Lbs, 8-ply, 19/32"
I'm not a big fan of the M/T tires strictly for the road noise, winter driving and rapid wear. Besides, I don’t drive a lot of mud in the desert West. Folks in the Southeast USA might have a different story.
What do people hear about the KO3 tires? A lot of spray about GMC, but no actual substance from BFG.

I know they like to spray about their KM3 tires.
Bottom Line: I'll wear out the stock tires before investing $2500 in another set of shoes (unless I get sponsored in some way

). By that time, they will probably cost $3000 for a set of 5 with inflation. Who ever said off-roading was cheap?
