You should be fine doing a straight swap. My 335i coupe has the sport package with staggered summer tires, but for winter I have a separate set of 17-inch wheels with 225/45R17 tires all around. I do the swap myself and have no issues.

If you want to go up to 19-inch wheels (not sure why you would, but throwing it out there) the OEM sizing is 225/35R19 front and 255/30R19 rear.
