What fitment issues are you concerned with? I was under the impression everything checked out. And you probably already know this, but the 265/30 will be nearly 1/2” shorter sidewall than a 255/35. That’s really putting that rim close to the asphalt.

My concerns are clearances, weight and getting the widest tire tread width.
When I saw the pics APEX posted with their test fitting and the Falkens, it was just too close for comfort. I realize that's the largest performance 265/35, but the rest are not much better. The PS4S has a 10.7" section width, only 2.5 MM more clearance to the front suspension, I think that's too close. It also weighs 27 lb.
While I'm blown away by the aesthetics of the VS-5RS in Satin Bronze, even more important to me is how much unsprung weight I can shed with the 19.1 lb 9.5x19, the 265/35 claws back some of the saved weight.
However, I did change my order for 3 reasons; 1) I realized the 265/30 was a tiny bit below O.E. load capacity, 2) I (also) suffered a blow out of a very low profile tire years ago and a 3.1" sidewall @42psi seemed too risky, and 3) I believe the car would need to be lowered to look right with the 265/30 3.1" sidewall.
So, I went with a sacrilegious compromise, the 255/35 Mercedes* Pilot Super Sport. The reasons I chose that over the BMW spec PSP4 are because of the weight and tread width.
255/35 BMW* PSP4 26 lbs 9" tread width
255/35 Mercedes* PSS - 24 lbs 9.2" tread width
(There is a 2nd BMW* PSP4 that shows a 25 lb weight, but still the 9" tread width)
With the 255/35 Mercedes* I get wide tire width, maximize unsprung weight savings, a relatively safe sidewall height, easy clearances and compliance with O.E. load capacity.
Our ZTK front fitment of 245/35 with 35mm offset vs 255/35 with 25mm is fine, top is .1" closer to fender well, inner wall is .19"
further from the suspension and outer sidewall .59" further out than stock.
The only slight compromise is that the 255/35 ideal rim width is 9" but the range is 8.5-10" so the APEX is fine@ 9.5" and even more with the 9.2" tread width.
