18 inches from the accessories without modifications ? V60D5

Good day, from next week I will be a proud owner of a V60 D5 FWD Autom. his vehicle has Njord rims in 17 inches and these should serve as winter rims. After a long search I found the Volvo at the org. 18 inches aluminum has a very large ET ( 55). Most aluminums from the accessories have however ET45 the maximum what I found was ET50 and in the ABE ́s stands that the rims have to be entered and inside in the wheel box on the axle 2 have to be sniffed around on the plastic cover….what I do not want. Is there a solution or does someone know rims from the accessories with higher ET? Thank you in advance for your answers. Greeting Mykael
