my 991 came stock with 20” sport technos, 20x9 front and 11.5 rear. 245/305 tires. comes oem like this depending on wheel option, not really stretched at all. you can run 255 if you like, theres plenty of room. i have bbs wheels also right now, bbs offsets are always very very conservative. if you want it flush you’re going to have to run 12-15mm spacer in front.

245 tires wont be a stretch on 9" wide wheels. the tire brand will be the main factor in how round/square the tire shoulder looks.

You probably can find the acceptable rim width and other specs for tires on the manufacturer's websites or Tire Rack's. I believe the stock front Pirelli and Michelin tires in 245/35/20 will fit a rim 8" to 9.5"

Now, I have sent the Brixton back(long story) and ordered the FI-R's. Hoping to go back to the stock sizes and it seems I can.
The PS4S seem to look more round compared to the square looking pirellis

Stock GTS is 20 x 9 fr 245/35/20. But I now run 265/35/20 Goodyear eagle F1 Supersport RS. But i needed to change castor. I have E-Motion adjustable control arms.
rear is 20 x 12 stock. 305/30/20 is stock. But looks slightly stretched. I have run 325/30/20 no worries at all.
