I have the 19 inch wheels and Nitto tires.
I am thinking of buying those again, because my Hi dolla Michelins
are barely going to make 25K.
What is this forum opinion on that?

I am surprised that you have 19" on the 2003 4.6is X5. I thought all of those were equipped with staggered 20 inch wheels?
