Will these tires fit?

I am wondering if 285/75/16's will fit on my Taco with 2" spacer lift up front and 2" Toytec add a leaf in back? I also have front tube bumper...

 

285/75R16's are doable but may require some fender liner modifications to keep them from rubbing in the front. Tires are like shoes, some run larger than others so the amount of modifications required may vary. Also, if you are planning to run them on your stock wheels you may have trouble finding someone that will mount them. The stock 16" wheels are only 7" wide. 285/75R16's are only approved for wheels that are 7.5-9" wide, (8" is ideal).
