Can I fit 215/40/R18 tyres on my R18 OEM JCW Wheel, which currently fit 205/40?

Is it possible to buy the next set as 215/40/18 tyres for my car (2019 John Cooper Works) which currently has 205/40/R18 winter tyres on OEM 18 inch JCW wheels?

I noticed a set of Michelin Pilot Sport 5's are 20% cheaper, is there any benefit or drawbacks of fitting these slightly wider tyres, if they even fit? The size is not admitted on the tyre pressure label. Thanks
