Aftermarket wheel choices

We have a Westfalia Sven Hedin on order and it comes with 16" black steel wheels as standard and I just don't know whether to replace them with 17" alloys although that's a cost I could do without but will the van look right on those 16" wheels? Also if we were away and got a puncture there is no spare wheel so I just wonder are 16" and 17" tyres with the right load bearing stocked by normal tyre places?

I have had two Svens. The first was on steel wheels, my current one is on the factory alloys. Personally, I thought the steel wheels looked fine.

That's good to know as ours comes with 16" steel wheels we have ordered the exact same colour as yours it looks fab in grey our wheels are black
