I started at 35 psi and switched it up every tire rotation to see what I like best.

33 was a bit better ride but lost 1 mpg for some reason. 30 and 28 was a bit soft for my liking for hwy, and I'm back at 35 psi which performs better for my dailly driving.

Probably a slightly different ride depending on 2 / 4 door, what type of load/weight your carrying, and wheel width as it will produce a different result with a chalk test.

This was my trial and error and I've settled at 35 psi for now.

I've tried a bunch of pressures as well, everything from 28-40 psi. I have kept it at 30 for a while now and been the happiest. Solid ride, takes bumps and potholes nicer, and I get decent gas mileage (18-19 mpg highway).

I run mine at 30psi and like it a lot.

I run 28 psi on mine. 325/65/18 on a 9 inch wheel. Nice flat spot contact and a great ride. Ill up it a bit to 33 for a long highway trip or hauling my camper.

I didnt know duratracs came in 325? Where did you get them

315/75R16: Run ~29psi front, 27psi rear....gives the flattest contact patch on my 16x8 rim. Airing up does save a bit in gas, but not enough to justify replacing tires more often because the center wears out.

From Goodyear...

I buy all my tires from a local shop called steves tire and boosting. But you should be able to get them anywhere selling Duratracs.

Definately chalk test hem to see for your set up.

For me, that worked out to ~29 front and rear.

I run 15 off road.
