I'm confused, why do you need to seal those joints

I'm glad it's not just me!

Depending on the brand of wheel the powder coating can be insufficient down in the bottom of that area. The sealant is there to stop moisture etc from getting in and rusting the area. I had a set of king wheels on my rangie that were quite bad for this. A set of roh wheels on my gq were sealed from the factory with a translucent silicon. The difference between an $80 wheel and a $60 wheel I guess.

I would use either a sikaflex product or some form of good quality roof and gutter silicon.

Roof and gutter would serve the purpose of sealing out moisture, however if it was mine I would go for a paintable silicone so I could paint it to hide it.

You will want to get the amount of silicone exactly balanced around the wheel too...

Or it will be a bitch to balance

Use a paintable sikaflex if you use the smelly silicone ( like roof and gutter ) or others that smell like a rotten armpit , it is corrosive and will lift over time. You want the stuff that the truck body buiders / horse float makers use. Its a sikaflex , but not sure of the number. put a uniform bead around the joint then spray over with windex or similar and then use your finger to wipe of excess to leave a nice filet sika weld. Have seen white and most likely comes in black.
For the intended purpose you could also pour some killrust paint in there while the wheels are laying flat on the ground
