Alloy wheels

[X3si]

Hi after some advice on the confusing topic of wheels and tyres my 2006 e83 x3 has the same size 17” wheels with same size tyres , I’m looking to put 19” on from a f25 x3 but they show as staggered size not the same size all round , after reading you can put them on and you can’t because of diff issues , is it possible or not and should I stick to 17” or 18” as they have matching tyre size .
