16'' or 17'' !?!?!?!?

285s or 255s?

Both are 33" tires.

Looking good. I recommend extended brake lines in the rear at least if not all around. Longer bump stops all around too.

 

Also if you flex, trimming will be required.

Definitely have to remove the mudflats and trim at the back of the front fenders near the bottom by the mudflat mounts. Not much if it's on road but if you're flexing, it will be more.

 

Looks like a dang good setup to me! I think you will be very happy. If you wheel hard you will have to trim quite a bit with 285s, I had to trim a bit and I don't "wheel" it. Like geek said, kiss your mudflaps goodbye.

 

if I went 255 would I still need to trim? and bye bye mud flaps =D lol
