Mine is a DD. In order to get a full footprint out of the tire on the street I run at 27psi front, and 23 in the rear. Even with the C load rating, the XJ doesn't weigh enough to get a full footprint at any higher pressure.
A TJ weighs marginally more than an XJ. About 500 lbs. based on the ones I have worked with. I would say somewhere between where I run and 30 psi would be ideal. Best way to find out is just air them up to 30 and air down a pound or 2 at a time until you get a full footprint.
Ordered my DuraTracs Friday night. Expecting them Wednesday at latest. I'll post pics. 33*12.5 on TJ.

Ran my 33x12.50's at Hardrock ORV in Florida this past weekend and I was getting places with the rear limited slip and open front that a simular Jeep on 33x12.50 BFG AT's that was locked front and rear could not get. The BFG's packed fully as it had been raining, the Duratracks Cleared easier than the ATs and if you look back I have posted that i liked these more than my BFG AT's taht I have on my 4Runner and now I'm completely sold, every tire out there was packed with mud, so it was simply which ones had the most side bite, and which ones would clean out the best, if I got the tires spinning, i could go anywhere I wanted to go.
This weekend had some dry rocks and sand as well, I aired down to 22psi which was the lowest I've ran them and even scared up the sidewalls on some sharp rocks with NO problems, just conform over and GO.
VERY impressed, there was also another Jeep there running the 33x12.50's but was locked - he made it up the Roller Coaster in the RAIN, it's a Damn hard climb without the rain, he was one of only 3 to make it out of about 15 to try it in the rain. go Duratracks.
Can't wait to get a lunchbox locker in the front of mine and head back, going to rebuild the rear LSD now as well cause it's kind of loose but I daily drive so the LSD will work for me i think.
About 5k miles on mine with NO cupping, time to rotate them though.

just read most of this thread and really enjoyed looking at all of the photos. Thanks for posting them up. I was initially looking at a set of MTRs with Kevlar to replace my dieing BFGoodrich All Terrains. However, reading this and seeing that the Duratracs are, in fact, more of a hybrid and a clear step above a regular All Terrain i think they might be a better fit for me for the following reasons:
1) More siping then the MTRs which will benefit me in snow and street driving in rain (we get lots of both in Vancouver)
2) MTRs are currently all on back order haha.
My question is this ... how have the SIDEWALLS held up on the duratracs. The biggest gripe with my BFGoodrich All Terrains has been that the sidewalls are literally leaking air out of them, while still holding the jeep up somehow .... Please let me know what you thought of the strength of the sidewalls of your Duratracs and if you got pics of any damage and a story of what/how you did it .... THANKS!!!
Tires are awesome, BFG AT's are my old favorite, these are my new
