Thinking about changing the stock 16" front wheel / tire on my 07 Ultra and need some help.

What's the largest diameter laced wheel & wide white wall tire combo that I can run without raising the front of the bike higher? 17"? 18"?

Thanks.

 

18" is about it

 

Pretty much the 18's as anything else you wouldn't be able to reduce the tire profile low enough to compensate for the added diameter. A 21" in the front WILL raise the bike. Not a huge amount, but definitely noticeable. Besides, the 18's would probably look the classiest on your Ultra anyway.

Also, if you want to go with a reasonably priced option, believe it or not, check out a couple of the HD options. Might give you decent price break when all is said and done.

Good luck.
