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?
