This car doesn't do well with the 21s. I went to 20s and haven't had issues in 40k miles on it so far.
My 2022 Audi RS7 has 22 inch rims and 285/30R22 tires front and rear and no issues in 4 years with bad roads. It's the design of the s class suspension etc that makes it prone to popping the tires along with their 21 inch rims. But the fact Mercedes went with thicker tires for the s63 tells me it's fine for the s580 as someone else did it on this forum without problem with rubbing etc.
Honestly the ride is much smoother and perfect with the 20s on the s class.
