I am putting a 180 MM tire on my 07 RG using a FBI Fat Bagger kit. According to the paperwork I need a HUB width of roughly 6 3/4 to 6 7/8. I want to run a stock Harley take off or fat spoke wheel, but interested in hub sizes people have with 180 tires.

One side needs to be 3.769 and other side needs to be 3.063. Can you guys tell me what wheel size, tire size and hub width please.

Example - 18"x5.5" Hub Width 6 3/4 with 180 tire on Stock 2012 Rear wheel (and type).
Thanks!

My reading of their instructions is that you need a standard Harley-fit custom wheel. The spacers will reposition the wheel on the axle to give tyre to belt clearance for the wide tyre. Or you could buy a suitable wheel from FBI! There are HDF sponsors who can supply wheels.

 

I did this when I made a 09' fender on my 08' SG ...and 180 tire on a 5 1/2" wheel. The wheel blank was 3/4" thick

 

Very Nice! So instead of buying the kit you just milled new hubs for your custom wheel?

 

Kinda, lol.....they are turned on a lathe. It was my winter project a few years ago to install a 180 on my 08 SG. I did a thread on the entire build. This isn't a kit. The "custom" wheel is a 5 1/2" polished aluminum blank.
