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
I've never seen anyone run that set up on 373 wheels. The 255/35 on the 8.5" wheel isn't an issue at all. The 295/30 on a 9" wheel is going to have quite a muffin top. It looks beefy on a 10" wheel.

First question is do you have xdrive - because if you do, you definitely should NOT be running a 255/35/20 285/30/20 setup.
