what size tires will fit under a leveling kit?

I bought some 285/60/18s for my taco, along with a leveling kit.. will the tires fit after its
Leveled? Or will I have to cut into the wheelwell? And if so how much will I have to cut and what would be the best way to go about that? Thanks for the help. I'm barely startin out any advice is greatly apriciated

 

With the 285/60/18s you'd probably have some rubbing issues! Trimming and wheel spacers might be in your future. I don't recommend spacers though...

 

Most likely have to cut. Best way to go about it, turn the wheel and see where it rubs then cut...might even have to chop the cabin mount to allow for the rear part of the tire.

 

Chop cabin mount? Is that difficult? And why not spacers?

 

Size of the leveling kit would help.

 

And wheel specs...
