i have a 2006 supercrew fx4. I was wondering if a LT285/65R18/E would fit with no rubbing. I have a 18 in wheels. I really dont want to lift it or nothing. i just want a more aggressive tire. Thanks (bfg all terrain)

 

I believe they will fit on the stock rims. For reference, here are those tires on a 2" leveled FX4:

This guy has even wider tires on rims with backspacing almost the same as factory rims with no level/lift and his do not rub so I think you'll be ok:

They will fit easily.
