Updates From +5 Sidewall Ratio Members?

Still looking to get rid of my factory 21” runflats, and replace them with Michelin Pilot Sport 4 SUV tires with +5 over factory sidewall ratios (e.g. 40 to 45 front, 35 to 40 back).

Any new updates or feedback from those of who’ve gone this route? Anyone notice the extra ground clearance? In the event of a flat tire, would there be any issues with using the factory size 21” spare?

Thanks…
