You simply aren't understanding. What it says on the tire means nothing at all. Might as well not even look at it. It lists the maximum possible pressure the tire can handle without exploding. You do NOT want to fill it to that pressure. It really doesn't matter how old the car is and how new the tires are. If that's the case, then the 2014 car someone bought brand new last year has an outdated placard since Michelin released a new model tire last month. Now THAT makes no sense does it?
If it's bias ply I'd understand. But bias ply has been obsolete for much longer than these cars are old.
It's just simple fact man. Ask any professional auto tech or tire salesmen and they will all tell you to go by the placard and nothing else. If you probe, they'll tell you everything I've been trying to tell you. Ignore the tire numbers and use the MB numbers.
*edit* I'm not going to take this threadjack any farther. I've said what I need, now I'm through with it. Apologies to the OP for derailing.*
