You are welcome.
Many tire places won't mount tires to rims that are out of the MFG's rim range. The warranty, if any, might not be honored, even if a tire place does mount them, or if someone does the mounting himself/herself. Tires can wear unevenly and have poor handling characteristics on-road. It may be illegal depending on where one lives.
Why do you want to run wider tires?
What vehicle will you mount them on?
Will this vehicle be used only off-road, only on-road, or both on-road and off-road?
What is the stock tire size?
I am considering all possibilities, part of that is figuring out the range of tire choices i could run with the wheels. It is going on a G55 AMG with wider arches, so while function is most important, ideally some aesthetics would be great; i.e. if i can avoid spaceship fitment, it would be great. So i am trying to figure out how i can "fill out" the wheel arches a bit and flush the wheels and tires to the body.
The vehicle will be used, at least when i put on the beadlocks, for light offroading/campings; mostly overlanding.
Stock tire size is 265/65/18, if i recall correctly.
