Tire rec’s

205/40/18 Neo gen’s on a x9. Today I fitted everything just to have to compromise stance to a point I refuse to do any further. I do not want to raise the car any more so only option is changing tire size due to not even getting a half a turn without borderline buckling rubbing.Do I get another 205/40 with a less beefy sidewall or do I bite the bullet and get a 205/35. Don’t want to run anything too sketchy but I understand it comes with it. Thank you for your time
