Hey upstate 650, you seem pretty educated on the tires, I was wondering if you can help me decide

I am running factory OEM wheel (373) at 8.5FR and 9RR, I want to swap out my crappy dunlops for pilot sport 4s at 255/285 or 255/295, do you have any experience or know anyone running those setups? I am worried that 255 will bulge on the 8.5 fronts, and 285 or 298 bulging on the 9 rear, and if those fitment does work, what are the draw backs if there are any, performance, ride quality, etc?

advice would be greatly appreciated
