All of the e53 wheels that are 18" or larger can be mounted on the 4.6is & 4.8is. You can use all of the 18/19/20 inch size tires that I posted previously (in both threads). 
Here's a link to all of the e53 X5 wheels: All BMW wheel styles X X5-E53 | BmwStyleWheels.com |
OK, thank you again. I have found several sets of good looking 18 X 8.5 wheels, but no 18 X 8 wheels. I was reluctant to get stuck with an 8.5 that would not work on this car, since it only shows the 8" as being compatible. But, if all of those wheels will work, that opens up a lot of options.
Thank you
