What PSI are you running on your 33x12.5x15 Duratracs?

I know there are a few threads on this, but I didn't see any recent ones for this exact tire. I figure with time people have figured out the optimal pressure. Also, the range of answers in the other threads is so wide it's not helpful. DTD set my tires at 30 psi, it drives fine but not sure if it's optimal. I figure I drive 50% highway, 40% city, and 10% offroad.

33x12.50x15 Im running 31. They are "slightly" overinflated (30 would be perfect) and I ran 32 for my 2200 each way mile trip to Moab, but I drive mostly highway, and the compliance and dynamics are slightly better. The "optimal" for tire spec wise is probably about 28-29psi.

I have this combo and usually run 32 highway and 20 off road. Sometimes 15 sometimes 25. I do 25 off road when we do a bunch of smaller trails, fire roads, and have pavement in between. It's still softer and safe to drive at 55 or below.

The shop that installed my 33" 12.5"s on 15" x 8" CRAGAR SOFT 8s (local shop) Set my PSI at 32...had tires ready when I got there....I had them drop them to 26PSI...this is on an '04 TJ no back seat no HT, no spare, but after market bumpers on OME SL and 1.25" BL......wear has been great...ride is even better and the DURATRACS are shininn' like the SUN on and off road!!!!

I ran those for about a year at 30-32 and had even wear. Good ride too.

That is what I was thinking. I currently have em at about 30 psi. wear is even, but think I only have about 2200 miles on em.

Great tire so far, loving it!

Mine shipped at 35psi which is noted as maximum pressure on the sidewall. I dropped to 29psi and have no complaints. I've only got a couple thousand miles on the tires so far, so I can't really speak to wear, but the ride is decent there.

DTD shipped them at 35 psi and I dropped it to 31 psi. So I'm usually 30 to 31 psi all around.

Sounds like anywhere from 28-32 is ideal. I'll set mine at 31-32 then for now to allow for some TPS leakage. Thanks guys.

I agree, I used to run 30/31 in mine, and 28 in winter for extra traction. This was on the TJ.

32 here. Anyone notice a difference in mpg between 28-32?

Edit: probably not any difference. Read this after I posted above. http://www.popularmechanics.com/cars/news/4199963

If 28 gives a better ride and no mpg benefit, I guess I should switch to 28.

I just bought a set of 33x12.50R15 Duratracs and they were at 30 psi. Very nice tire.
