35's do to 33's

Hey i currently have 35x12.50's on my truck right now and they probably wont last mue much longer than 2 or so months. I was thinking maybe putting 33's on it to save a little money and pick up a little extra speed from them compared to the 35's

I also have a 6in lift on the truck right now and im not totally sure what its going to look like on 33s? Anyone have pics of that?

But let me know what you guys think
