Bigger wheel question

Hello Experts,

I have a Honda Accord Coupe (07) with original wheel size 16 (tire 205/60 R16).
Currently there is no modification on the vehicle.

I am planning on putting bigger wheels that is 18X8 (50mm offset) with tire size 225/50 R18.

I have the following questions:
> Will this wheel and tire fit in without any alteration?
> Will this have any major impact on the overall performance of the vehicle?

Looking forward to your advices and suggestions. Thank You!
