Awesome, I just have a couple questions...

So super-single rear tires for semi trucks... Why are they more economical? Here's my train of thought.
I read in the article that they can weigh 800 lbs less than duallies, so obviously that's going to have a big effect on starting/stopping/accelerating---but the fuel savings is also due to less sidewall flex, right?
In a setup with duallies, you're going to have two skinny tires with sidewall flex. In a super single, you're only going to have one tire's flex to deal with.
Is this right?
