Any body know what is the largest tire you can put on the rear of an 06 Road king with a 4.25" wheel?

 

i have seen bikes witha 300 on the rear. if you want to stay with the stock fender a 150/80-16 is as big as you will get. with fender mods narrow pulleys and larger jackshafts you can get much bigger. try fat baggers inc for some research

 

check this site.

be sitting down when you read the price.

 

You can go real fat with mods...&nbsp\\; Kit itself is about 3K.&nbsp\\; Then install, fender paint, and tire/wheel.&nbsp\\; A cool look, but at a steep cost.

 

I'm running a 160mm metz on a 4.25 wheel on an '06.&nbsp\\; My buddy is running the same setup on his '06 street glide.
&nbsp\\;No mods, no problems!

 

Thank's everybody

 

Yep I ran a 160/60 Metz on my 07 SG with no problems...
