Wheel arrow???

[NavyCWO]

I have a 1991 R 100GS. When I removed the wheel to clean up the brakes and do a shaft lube I noticed the inside of the wheel has an arrow pointing toward the center. I can't find a reference to this and also can't fine a corresponding arrow on the drive hub. Can anyone give me advice as to what this is and if it is important to the wheel installation.:dunno

Maybe some sort of instruction to the monkey putting the tire on at the factory? Put tire here?:laugh

A picture would be nice. I've owned several airhead GS'.

Probably pointing to the portion of the wheel that makes it tubeless.

Is it just to tell you which way the axle goes in?:dunno

I tried to lighted the arrow with white paint. Note it's at the bottom of the wheel.

Maybe location for a specialized BMW tool?

It appears to be pointing to the lug-bolt hole. There should be four arrows! :jester

I tried to think of something funny and failed....

I wonder if the wheel indexes somehow? It's pointing between those two holes.
