rim and tire? Help before I do something stupid
Not many problems with upgrading to 17" because it was a factory upgrade when the car was new. 18" and above you need to do your homework. Ride will suffer but maybe that's not a priority for you. Also, be cautious of fakes as it's pretty easy to change a stock MB wheel into a AMG looking one. Most MB wheels have part numbers on inside of spokes.
Good luck.
I tried searching other post for answers and the closest I got was people saying they run 245/40/18 but nothing about 245/45/18 (in front at least)

I don't care too much about the ride I work less then 3 miles from home. The #s on the spokes was one of the first things I checked, there true amg. Thank you for your concern there is a lot of knockoff mb wheels out there.
made (or, at least be ready to modify).
if the car is otherwise left unaltered, your car may be okay but upon hard
compression the tire may rub.
if you intend to lower your suspension, the odds of the tire rubbing increases.
if you have cruise control, and running staggered front/rear, this mismatch
will cause the cruise to disengage.
if you're planning to run 245/45 all the way around, your odo and speedo
will read lower and slower than it actually is....by about 5%

front rims with 245/45, somewhat implying that the rear tire size may be
different. since it's unlikely he would have staggered with 245/45 all the
way around, the likelihood of mismatch, ergo cruise control malfunction,
increases.
you didn't post the tire sizes for your staggered configuration, so I have no
opinion on the suitability of your set up.
I have staggered on mine and the cruise feature is fine. so the devil is in
the details, ie the rolling distances between front and rear tires must be
within the narrow window of acceptability
plug in both tire sizes. keep the differential between them to within 2% and
you should be fine
