It all comes down to usage/what you want.
End of the day you can get a better 235/40/18 that will grip more than a 255 for the same price due to the common size discount.
I ran 235 NT05's, low with a decent sussy setup (6/8 coils, camber bushes, pineapples, sways, hicas lock) and had traction right through second with 330rwkw
