Neils, I couldn't find any pics of wide body CMC running 17" Fuch. Quite a few wide body CMC with 15" Fuchs
For a matter of visual reference, these pics are of SOC member in Arizona, with 17" Fuchs on his normal fender Speedster.

Here's a pic of another SOC member (Kevin Zagar, owner CoolRydes Customs) with 17" Fuchs on his normal fender Speedster).
Hope this info is helpful for you!
