Let me amend this...the tire you choose may change that. You might be ok with those sizes in the Toyo T1R and Falken FK452.

 

+1 Technically +22 with a drop on 255/285s should not rub. When deciding on the tires you are going with, do some research from the tire manufacture sites and get the actual sizing of the tires. Not all tires of the same size are the same size. If you go with a "smaller" size and you still rub then go ahead and plan on doing fender modifications.
