I have an 05 f150 xlt and I'm putting a leveling kit in it. What size rim and tire are the biggest i can go with now? Would 33x12.5x20 work?

 

2WD or 4? Rim diameter size doesn't matter, just width and the amount of backspacing (which is needed to determine if those tires will fit)

 

It is a 4wd suspension and everything is stock besides the leveling kit and it's a 2 inch leveling kit

 

Those tires will fit on pretty much any 20" wheel that is 10" wide or under

If you narrow it down to specific wheel, you can double check to be safe.

 

I found a set of rims and tires for sale that are 33x12.5x20 will those fit without rubbing?

 

95% chance you'll be fine. Only way those wouldn't work is if the wheels are super wide or have ridiculously low backspacing.

Got a link maybe?

doesn't day anything about back spacing at all. Just wait for the guy to respond to me about them

 

I was hoping it would be a wheel I'd know, but I'm unsure about those. If they're 20x10" with up to -24, you'll have a bit of rubbing, but trimming should take care of it. But if those happen to be 12" wide, which they might be, they may or may not fit without some rubbing after trimming.

I will say that I don't think that's a particularly good deal. Those tires are $1400 or so new, and the wheels are maybe $1000 depending on what they are. Depending on how much tread is left, those tires are worth maybe $400+ and the wheels maybe $600 or so. That's my opinion anyway. And you should definitely check to see how many balancing weights are on each wheel. If any are double stacked or over 10 or so, I would walk away. I'd want to see how they clean up before buying them too.
