Tire size 255/50

Will 255/50 r21 from an iX fit the x5? I know it’s taller but gives the 21s a little more meat

Thanks

Center bore and bolt pattern between g05 and iX match. So wheel will mount. ButIf it fits, outter diameter will be 4.4% larger, very noticeable difference. Car will drive differently. 255mm width is quite a bit narrower, meaning braking performance will be compromised. I don’t see a good season to do this.
