you'll need more than that...
I had 2.5" spacers and had to do another 2" BL to keep it from rubbing. Also with 285's make sure you have a lower offset wheel, or else the tire will rub the UCA.
If you really think about it, though...how much can you really flex out a truck sitting stock on 33" tires? Not much. Way less than you can with 31's or even the stockers. Stick with 31's if you don't want to lift it.
There are hundreds of threads like this and we all say the same thing, and the n00b always disregards which leads to hundreds of "ugh now I'm rubbing" threads.
Yes, the idea with building a truck is to fit the biggest tire in the lowest truck, but we've all learned from experience that to fit 33's (285) you should be running at least a 3" coil kit and 1" Body Lift(if you don't want to pound/trim).
I've seen a third gen running 37x10.5 tires on a 2" Tundra coil lift...but he cut the piss out of the entire truck and it looked like balls.
In the end, it's your truck, and you'll do with it what you will...just make us proud.:driving:
