I currently have Run Flats 225/50 R17 94W on my 525d, however Michelin Sports is only available in 225/45 R17 91Y - so can I replace my existing 225/50's with 225/45's without changing the Rims - and is it a good idea

Thanks

Do not know about UK but in Italy you can use only tires that are approved for the specific model and the size you are indicating should not be suitable for the E60 as smaller.

They will fit but it will affect the speedo reading and gearing slightly...

Personally, I'd fit another brand - I'd recommend the Goodyear F1 GS-D3 from the available brands...

I had the same concern as you. After checking around, I went ahead and put 225/45R17 winter tires on my 530xi (stock all weathers are 225/50R17). The 45 produces about 3/4" lower profile compared to the 50. Small change to speedometer and gas mileage. So far, no problems. It's not optimal, but I don't believe it's a problem.
