Non-Sexy MPG Advice

This is about as sexy as John Goodman in a speedo but it definitely works, particularly for heavy pickups.

Keep your tires aired up rock-hard.

This is a must for folks with firebomb tires but it makes a big difference on other brands as well.

I use 235-85 E rated tires and I keep them inflated to 80 psi, front and rear. Any more and the tire starts to "crown" - bulge out in the middle of the tread. That will wear the center of the tire out quickly. Not recommended.

My truck is very sensitive to this. If the tires get down to 70 psi, I lose 1 MPG. At 60 psi, 3 MPG. Ask me how I know that. Don't gundeck the tire inflation.

Ok I got a 6700lb F250 I run Yokohama geolanders 285 75 16. wHAT do I run front pressure and rear pressure for good ride and best tread wear? At 600 for four I need to know. Tate
Is there not some consideration for front engine weight on the tires and the lack of weight on the rear tires? or is MPG and tire wear two different things? How can the max pressure from the manufacturer account for my trucks weight when they don't know what vehicle their tire is going on? Am only looking to learn TAte
