looking at them they need to be bigger. and for me, Black. i'v seen it with mercs that bigger wheels can contact the bottom of the front lower spring seats, go too big without much lower profile tyres and you will mess with the speedo too. with alloy's you will need longer bolts. if your keeping your spare as a steel wheel. keep the shorter bolts handy.
Paint them Black, you can get the wheel insert trims in Black, if you’re not happy with them buy some Alloys off a Vanio as they’ll be weight rated to a Vito as it’s a heavier version.
I think this is it I bought some better 16 inch tyres so will stick with the current steel wheels and then keep an eye out for alloys
Vitos also have issues with front wheel alignment and can be prone to scrubbing the front tyres badly so I’d advise against going bigger than standard. Wider tyres = less MPG Lower profile = harsh ride, particularly with vans as the suspension is already stiff to take the loads. So I’d stick with what you have
