9x18 et45 front, 10,5x18 et60 rear?
The rear might be a problem 18x10.5 +60mm should work in theory, but in real life they might have a big chance of rubbing the inner suspension if u are lowered. Again 280/60/18 sounds like a very odd size. I would suggest u 285/35/18.




Roswell is correct that an ET60 on the rear with a 10.5 wheel will likely rub on the inner suspension.
Your widths of 260 and 280 will be very close as well if they don't rub the fenders.
If you're not lowered, 260 width on the front should be fine on a 9" wide rim (no issues running 255s on the front on a car with the AMG sport suspension).
