Change from run flats and 205's to 215's

Looking for confirmation that changing from oem run flats and increasing width from 205/45/17 to 215/45/17 is a sensible thing to do. No issue with grip from the run flats just that I find them very noisy and not very forgiving on our non-maintained roads.
Was thinking Michelin Primacy 3 or maybe 4. 215 seem to be 10 quid cheaper a corner.
TIA for any input.

Don't think you should have an issue. You certainly won't have an issue swapping from run-flats to non run-flats and you should have plenty of room to run a 215 cross section.
