He put OEM wheels and tires on.
According to OP the OEM were factory 20s.
"instead of the factory 20s I didn't want."
I just have sincere doubts that putting smaller than original tires on a pickup will give that much of a fuel mileage increase.
Yeah. His truck came with 20's.
Others of his same make and model came with 18's.
He put 18's on, from the same make and model truck, with tires of the same overall diameter. The new wheel and tire package is lighter and will provide a smoother ride and less unsprung weight.
