285/35/22 in the rear will also work for your X. Fitment wise, you should be fine. You WILL ABSOLUTELY need hub centric rings.

Where do you live? Seriously, IMHO unless your roads are silky smooth 22's might deserve a second thought. The ride and braking suffers, and 1 pot hole is all it takes to ruin your day. Plus your suspension will be thrown off. Yeah they look great on a 4.8 but the X5 was made to handle and 22s throw that out the window. Having said that, If you do get the double duece, definitely go staggered!

Go staggered because 22x10 on the front is going to stick out even with 30mm offset, also you run the possiblity of rubbing with the plastic cover of the wheel well. Take it from me, I have 22x10 all around and not by choice, staggered was not an option on the rims I bought

i got 22's on mine it rides like crap and i live in pothole city nyc but the truck looks great i dont drive that often.its going to be a ruff ride if you up for it get em its your truck its your decision i got 22x9 there slim wheels braking is ruff of course 22's are heavy i would of gone staggered but the wheels i have dont do staggered

Thanks guys. Ended up getting staggered 22x9 in front, 22x10 rear. Ride isn't too bad, will try and post pictures soon :)
