Just as an update.

I bought the wheels and tires. Took the new tires off the 7 series rims and put them on my original wheels. I could not buy tires for the price of these. New tires ripped off the old rims and put on the original X rims for only a total of $480.
I know the tires are a little smaller than the original 255/55/18.
Thanks for all the advise.
