I've searched through all the old posts I could find regarding this and still see alot of leeway about which direction to go regarding tire pressure on my stock 265's. I run empty 90% of the time and on the weekends I may tow the 6x14 trailer with the Polaris Ranger on it or my 22' bay boat on its tandem axle trailer. All are only about 130 miles round trip. What's the best tire pressure I can run to increase mpg on my daily driver without rattling my teeth loose?

 

It matters how loose your teeth are. Everybody has a different level of comfort. I used to run mine at 70 front and 60 rear and only air up to MAX when pulling any loads. A friend would get in my truck and tell me to let air out as it was to harsh. I guess I like it a little harsher than most.

The more air the better MPG so I choose for a little harsh.

My current tires I run 90 in front and 80 rear.. 105 is max.

Try a few settings and see what you can live with. I took my stock tires off around 65k and they still had some life in them. I think the higher air also helps wear as long as you rotate on a regular schedule.

Good Luck, Jeff

 

Take a look on the edge of the driver's side door. Our roads are icy "up here". I run about 45psi during the winter, and my tires wear just fine. Make sure you rotate them regularly, and keep your vehicle alligned properly. I would run around 65psi with my fiver. The maximum inflation on the side of the tire may not be recommended while used on your truck. It may also not be suitable when running empty, unless you want to wreck other components on your truck before their time. If I'm not loaded, I run a bit less in the rear tires than in the front.(Check the recommended pressures on the inside of the front door.)

 

I've found that 60 PSI is a good compromise between load handling, ride and MPG.

Well, I went to 65 all the way around. They were at 50. I drove it only a couple of miles and the truck feels better. The gosh awful dip in the road around the corner actually feels better with the tires pressured up a bit. Thanks for the input.
