TrafficJam · 10-26-2022, 03:42 PM

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!
