I've had 285/75R16 Duratracs on my JKU for almost 2 years now. Unfortunately, I wouldn't recommend them. While they look great and do perform well in multiple conditions, they don't balance well. If Goodyear could improve their quality control on this tire, I would have no problem recommending it. My next set of tires will not be Duratracs. I'll probably go back to BFG's.
I've been reading this thread on and off since I'm looking for a 33" tire for my Rover but missed this post.
I'm currently running a 32" Duratrac (275/65-18) on my Rover and have NO problems with it wrt balance or out-of-round. They roll nicely. After 20K miles in about 2 years they still have over half tread left and have done reasonably well in most off-road situations. I've run them in rocks, dirt, snow, sand, mud, gravel, etc. They were extremely quiet initially but have become noticeable with wear. I do a 5 tire rotation every 5000 miles.
My only real complaint is the usual one for a Duratrac - not strong enough for rock use. All 5 tires have significant tread chunking or tearing and gouges in the sidewalls. While these are E rated tires (my Rover is north of 7500 lbs) they just aren't strong enough for heavy rock work. Other than that they've been quite good.
I would easily recommend them to somebody so long as they weren't planning to do any significant rock crawling. For a dual-purpose rig, especially one that will see snow where these tires really shine, I think they are an excellent option.
