'm unsure... probably. However, to run 285 / 33" you should also look at adding wheel spacers to correct the rear axle width to match that of the front, as the pickup, like the cruiser, has a narrower rear axle than the front axle, hub to hub measurement) mine are 43mm spacers. I did run my 285's without them at one time or another, however, the rims i was using then were not my Original patrol pickup rims, they were trail dusters,and although they stated the EXACT same offset as the originals,(16" 0 offest) they were 7j rims , which pushed them out slightly. The 0 offset also seemed different, as they were more like -10 offset to be honest.
Dont stress about the speed scrub etc,... get the 285's and dont look back. 255's are only gonna make the slightest difference in certain areas, but in other areas the 285's will make the slight difference,... and so on.
Like i said,... the 255's are gonna be risky. No one keeps them, almost no one travels with them,.. its not a good call for people who wanna use their vehicles in the toughest conditions with confidence... just give it some thought. my opinion of course.
