Q At what point are tires underinflated ? If you look at the tires load rating. MAX tires P at 45 LBS. THESE TIRES ON THIS TRUCK ARE 31INCH.
That a big ass tire. for a little truck. then take in the what the truck GW is you will find that you can let air out of the tires and still not be underinflated.
So the contact patch not reduced. The control of the truck is not reduced. and the only other load is my big fat Be-hind.
As for gas 22-25 MPG. I could let more air out.
