Biggest and best tire I can fit on stock Performance Pack wheels

Hey guys, it's time for me to change my rear tires, I still have the stock 275/40-19 Pirelli P-Zero's on my GTPP. I'm wondering what the biggest tire size I can fit on the wheel is and what tires are recommended. I'm looking for high performance all seasons but I don't know much about the sizes or profile and how that matches up with the wheel. Thanks for the help!

285/35R19. Anything larger isn't getting you anything. If you can find a 285/40R19, it's closer in size to the 275/40R19.

It may depend on the specific tire, but for many tires 285/35R19 is the biggest you can put on a 9" wide wheel. Your tire shop may award you a new four letter middle name, but they'll fit.
