Seems very unlikely that any tire could change mpg that much (particularly on a truck, where tires are not a great source of resistance compared to the aerodynamics and weight). I mean, my brother's Pruis lost a few mpg when he put different tires on it. I suspect there is another issue causing the calculations to be off.
I lost about 1 mpg freeway when I put LTs on my '11 F150.
It's common that a high mpg vehicle like a Prius (or my Volt) will lose a couple of mpg when tires are new, especially low rolling resistance tires. After the tires wear in, mpg improves. It's far more noticeable on fuel efficient vehicles than it would be on a truck.
