Tire width is limited to what the rim can safely retain.
Make some calls to local tire replacement outfits to find out what they are willing to install. Get prices while you are talking to them. They won't install a tire that is not safe for the bike due to liability if it fails. You do NOT have to take it to a Harley dealer. If you are willing to pull the front wheel yourself you can take it to any shop and save the labor while you are at it.
