Well as you can see I put on Fatbob trees, 2010 Fatboy rim an Tire on my FXDC an a Deuce rim on back. After being blown all over the road by wind Im done with this setup. I got a set of Wide glide trees to add the 2 degrees to the front an bought a cool 21 smooth profile softail 21 rim for the front and putting the stock rim back on the back. Being blown all around at 80 & 90 sucks..

 

Seems like you cant leave that bike alone, can you? lol! I know what your talking about though, I rode a fatboy lo a week ago and when the wind picked up, it wasn't something I was use to!

 

Are you blaming the rims?

 

I've never ridden a Fatboy, but you're not the first I've heard complain about getting blown around from the side. I guess those bullet holes on the newer wheels don't help enough. But they sure look cool.
Strangely, I don't hear this complaint much from Fat Bob riders.

 

I have a Deuce rim on the rear of my Bob and OEM spoked on front. No problems with that set-up for me.
