Are running stock 18" wheels?
If so,this combo would work to give you a wider look and keep
your diameters within the proper tolerances:
255/40/18 front
275/40/18 rear
Thats about as big as you can go on a 18" wheel.
You may have a problem finding those sizes in the tire of your choice.

Folk erroneously believe that the rim diameter has an impact on section width. It doesn't. It also doesn't have a significant impact on overall diameter. As the rim diameter increases, the section height decreases to keep a wheel and tire set up within spec.
vendors are trying to keep everything within range.

The wheel "size" is of little relevance to how "big" he can go. The overall width doesn't change all that much based upon wheel size. The section width does and that will be based upon rim width.

I believe the tread width will be larger than the stock size tires he mentioned
