07 Continental gt 22 tire size?

[the tuscanier]

Currently running 265/30/22 on my 07 Continental
Would prefer a bit more sidewall if possible?

Have been advised that 275/35/22 or even 285's will fit but would rather ask what your running before a potential very expensive mistake if they don't fit!

Rims are 9.5"
Offset are et25 & et32

Thanks in advance 👍🏼
