Mismatching Tires Front & Rear. Any Problem?

I have a M760i XDrive and is currently running on mismatch tires (for about three weeks).

I have 245/40 ZR20 Michelin Pilot Sport 4S on the front and 275/35 ZR20 Michelin Pilot Super Sport* on the rear.

All tires have similar amount of tread, and their sizes are the same as the factory stagger set up.

I heard many tire vs diff issues for AWD cars. I am wondering if there is a problem with my setup (Considering PS4S and PSS are similar tires)?

Thanks a lot!

You're still using the correct OEM tire size (staggered fitment) so you shouldn't have any issues other than maybe some odd handling characteristics. The PSS and PS4S are similar, but vary quite significantly in the wet so you might notice some difference here and there but otherwise, under normal driving, should be about the same. The differential issues can arise when you change the tire/rim size outside of the factory staggered set up e.g. increase rear wheel width or tire width.
