GR Yaris - Replacing the BBS Wheels with wider ones

Our japanese friend GT-R GT-R GT-R uploaded a video about replacing the BBS forged alloys with Michelin Pilot Sport S4 tire combination with a wider one: 255/35R18 DUNLOP DIREZZA ZⅢ tires mounted on a 9.5J +44 ADVAN RZ-F2 rim. Terrific!
Question is: will this (or similar) combinations be possible in Europe (Germany)?
