[V15H]

Hi,
I have a standard e90 320d se fitted with style 156 wheels.

I have seen some wheels I really like for sale, they are R16, 7.5J ET13. They currently have 205/50/R16 fitted which I will remove.

Will these fit my car with my current tyres which are runflats 205/55/r16?

I believe style 156 wheels have an offset of ET34, does this mean I will need wheel spacers 20mm or a little more to compensate?
Sorry if this is obvious, but I have not done any wheel swapping before.

Thank you in advance.
