Tire size question

[AWe92M3]

Whats up fellow members

Wanted to find out if anyone here ever ran 295/35/21 front rather than 285/35/21 while still keeping the 325/30/21 rears? If anyone did, any clearing issues or any other issues?

You may want to reconsider, as rule of thumb with BMW modern transfer-case, the rotating diameter difference between front to back shouldn't be more than 1%
Your set up with 325/30/21 and 295/35/21 yields about 1.4% diff

I know when you get into the 21” tire sizes there aren’t many sizes available, but if they make a 335/30/21 you could run those along with the 295/35/21 up front.
