Some tire brands in a 285 are wider than others. I'm posting a coupe pic's, I had GY F1 285/35/19 supercar run flats on my 04 coupe, it's the widest tire in the picture. I bought a pair of PS2's 285/35 19's for my SRT6 and they were not as wide as the GY's, first pic from left to right is GY 285 - 2nd is OEM 255 and on the car is the PS2 285. Second pic is of the GY 285 next to the PS2 285. The GY is about a 1/2 wider than the PS2
