I posted this question in the tech section as well. I am shopping for a rear wheel and tire for my 07 Street Glide. The stock size is 3" x 16". I have an 18" wheel on the front, but would like to stay with a 16" on the back. Is there room back there to go a little wider? What is the maximum wheel and tire sidewall width that will fit comfortably?

 

I have a 3.5" x16" running on my Ultra, it should mount up the same.

 

I am running a 4.25" X 18 rear wheel on mine. I wouldn't think that it would make a difference as far as the 16" wheel goes. BTW, why do you want to stay with the 16" rear wheel, after you have already changed the front to an 18"?

 

I don't have an answer to that. I have been shopping 16" wheels and haven't really considered going bigger in the back. I have a Dunlop E3 tire on the front. I found the E3 that would fit a stock size 16" wheel and shut my brain off. I am going to do more research. Thanks for calling me out.
