Spare
I ordered my 540 with the spare too but not my X5. Just got an ordered spare for it from Modern Spare out of Ut USA. The rim is aluminum and lighter than the steel versions. Came in about 10 days with a jack and bag. Fit perfectly in the spot under the trunk. Even used the jack and tire tool that came with it to remove a wheel to test fit. All works great. Pretty sure MS could sell a fit for the G30 as well. I'm happy $450 later.
