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.

well my PJ's say 65psi but it didnt wear right so I played with the air, maybe this time i will leave it at 65psi and see how it goes I used to get good mileage to.
I dont mind the ride I've never had anything smaller then a 33 lol so im used to it. should I back it off some it wears wrong like the center my buddy got 50k on his 38 Pj's
So what PSI should I be at for the Track ?
