You're right that online it shows the difference. On the Conti factory tires, the load rating is just indicated as "XL" on both front and rear. It doesn't show the actual number.

My BMW center wasn't able to find any all seasons available to order and I called Tire Rack and they told me the same. But, when I do a manual search by individual sizes, I can find a couple of combos with these numbers. None are run-flat so maybe this was why they were not finding them, even though I mentioned I had the spare. Not sure.
