I've been looking for something to replace the runflats on the X3 M40i with the 21" rims.

I was hoping to go for the Pilot Sport 4 S tyres but I can't find them anywhere and Michelin tell me they are discontinued (despite them just announcing that they will ship them with the X3M Competition!).

I see that Continental SportContact 6 come in the same size and are also BMW Star rated.

Will 255/40 ZR 21 102Y and 265/40 ZR 21 tyres be ok on the 8.5J and 9.5J 21" rims? I know the X3M Competition has slightly different size 21" rims?

I assume these will be within tolerance for X Drive to not hand any issues?
