BFG K03s on 2025 G63?
Looking at 285/55/22 BFG K03s on a stock G63. Anyone have experience with these? Any rubbing issues or can they be installed and used without any issues?

What is the stock tire size for the 22 inch wheels? I have the 20 inch wheels and the stock tires were 275/50R20 and I went with the 275/55R20 BFG A/T KO3s and they fit fine with no issues. I will say they are close, but I still have plenty of space. If I went up to 275/60R20, there would be some rubbing at full articulation. Sorry I cannot comment on the 22 inch wheels, but I can tell you I LOVE the BFG A/T KO3s, they look amazing on the G wagon and the ride quality is excellent. They are also really good in all terrains, a big improvement over the KO2s that I ran on my other SUV. I highly recommend them!

G550
I have 275/55R20 tires (not K03s) mounted on OE wheels on my '19 G550 -- tires are about 1/2" larger in radius than the OE 275/50R20 tires. The place to inspect for interference is the outside edge of the tire hitting the plastic vent in the front wheel well area when turning the wheels. This larger tire size on my truck leaves a bit less than an inch of clearance in this area.
Best way to be sure is to ask your tire dealer to test mount the size you want and check the clearance when turning the wheels while on the lift. You don't want to buy 4 tires and discover there's a problem while driving home.

I am 99.999% sure these will not fit without modification. It looks like they have a 34.4" diameter.
At least for 2019-2024, the OEM 22's are 31.3" in diameter. 285/45/22's are the A/T size most of us used in the past and are 32.1" that just fit without rubbing.
I do not know about 2025's as I stayed stock, but I have to imagine they are similar.
