Hi Guys,
I have BF Goodrich LT265 R17 ATs on my 1997 Dodge Ram. I air them down to about 24 PSI when driving off-road in Utah. And air them back up to 35 PSI when back on the boring pavement.

What PSI would you guys recommend for highway/in town driving?

Thanks.... Jason ....

 

What do the sidewalls say? If they're 44 then I'd run 38 in the back and 40 in the front. If they're 35 then I'd run about 30 in the back and 32 in the front.

 

MiNe are up to 80psi and I run 60. It's a rough ride though

 

The max on my tires are 80 PSI.... I think I will increase my PSI from 35 to 45.

My truck on the highway driving around 65 or so will get about 16 MPG. (In town driving is around 13-14 MPG). Any thoughts on what increase ... if any ... in MPG I would in going from 35 to 45 PSI?? .........

 

Maybe 1 or so..... if that. May not even be noticeable. The biggest gain is in tire wear. higher pressure will wear the tire more evenly. (to a point.... too much pressure will wear the center faster.)

If you want to get REALLY berserk.... get one of the IR thermometers, drive your truck in a STRAIGHT line for a mile, then measure temp at both edges, and the center. You want all temps to be the same. Cooler in the center? Add pressure. Warmer in the center, reduce pressure.

Of course, the 'right' pressure will change with the seasons... and the load in your truck.
