"LT" tire pressures on Expedition

I read whats on the tire and do that. My rule is: Do not exceed the manufacturer's specifications. People try to outsmart the engineer who designed things. I do what the engineer said do.

Since you're trying to oversimplify it for the rest of us whom you appear to perceive as uninformed or not knowledgeable, go back and read the OP's posts and tell the class how your answer above is even remotely correct or "what the engineer said do."

I'll let you figure out why I said what I said.

And fwiw, to all the "do what the engineer said" folks, yes it is generally a safe practice, if not used out of context like falconbother's statement above.
However, being an engineer and also dealing with multiple engineers on a daily basis (but being on the practical application side of my industry, not the theoretical side), I can say heartily that "engineering" is an ever changing blend of the theoretical solution, the practical solution, the politics, the cost, the liability involved with the particular solution and the human opinion or error aspect.
Remember, believe nothing you hear and only half what you see...and trust but verify.
