Wider rubber is beneficial only within the design specs of the tire and what size wheel it’s meant to be on.

On the min and max of the tire’s wheel width range and beyond them, you’ll experience more negatives than positives. If the wheel width is at the tire’s max wheel width or more, expect tire stretch, and rim curbing to be more likely. If the wheel width is at the tire’s min wheel width and smaller expect sidewall bulge/flex, and reduced steering response.

Good luck in your hunt.

Edit: I’ve ran a few sizes of tires and have felt those effects back in my old 06 wrx, and on my current sti in autox. Right now I’ve gone from 265 to 275 on a 9.5” wide wheel both spec’d for 9.5 and the 275 does have more a soft, less dart-like? feeling than 265... not sure if I’m liking it yet. My brother had a similar experience too in his mustang (yes he autox’s that lol). He down sized the tire width so his wheel width is at the sweet spot.
