Kinda like the speed limit... I consider it to be the suggested speed you drop to at the top of the mountain
Seriously, though. Some vendors are super conservative, and some are wildly absurd with their ratings. I'm glad they give us a starting point, but after that, you get to see what they really can do.
Heck, I got 110,000 miles out of my 60,000 mile Michelin LTX's
guess what I replaced them with? Wasn't the 40,000 mile Goodyears that only lasted 30,000 miles!
