OK interesting..
Whiie on the phone with Michelin, the woman was talking about the 225/40/18 I bought were not the load rating required by the Ford ST. (which is 95 load rating)
So others said so what.. the car only weighs so much blah blah.
Then while she was talking i had a real epiphany.
It is the dynamic loads which are the reason for the ST higher requirement.
Going around a corner full tilt (which I love to do, a LOT) puts a much higher load on the outside tires.. especially the front one.
So IMO that is where the load rating comes in.
Suddenly I realize the service guy did me a big favor, and may have saved my miserable life.
So I am happy instead of pissed off.
I called him, and the dealer manager to say how I was an ass, and why the service guy was a hero.
Anyway, glad i did not just go find some dope to put the tires on.
Also the other tire place who also said do not use those tires.. And made me think well there must be some reason..
So yeah there was real reason. I guess I just focused on the size too much.
But now I know.
