Alignment for custom time size

This will increase side wall a lot compare to change to standard size of 17" which is 245/R45-17. But know the problem Costco, Walmart and maybe Samsclub will not install the tire because it different than placard in driver door. So I end up installing myself. I am plan to bring to Discount Tire for balancing. I am thinking about doing alignment. Is MB dealer will do alignment if tire size not regular? Can you recommend any shop do alignment for Mercedes?
