Yep, funney you should ask...
Edit: Even funnier because I can't type "funny"
Below is some of the text from an article I wrote for the Power Stroke Registry magazine about 8-years ago after replacing my first set of TXRs in 255/85R16.
Multi-Mile Wild-Country TXR 255/85R16
After replacing the stock tires on Pull Dog, we figured we would settle into a routine of new tires every Autumn. We drive more than average and that would insure that we were entering the winter season with fresh treads under our chassis. After two years had passed we had logged over 36,000-miles on our 255s, and our third winter was near. Our plan to buy new tires was scrapped, as our tires had much tread left.
All of us want our tires to last a long time. Tires are expensive, but getting new tires is a fun and exciting proposition. We were beginning to think we were not going to ever need a new set of TXRs!
The Second Set
The fourth winter after our initial TXR purchase was fast approaching, and our tire tread was still fairly deep. One afternoon while walking up to Pull Dog in a parking lot and scrutinizing our tires, I noticed a 3-inch long cut on the inside of the sidewall on our left-front tire! We doubt it was vandalism as who would take the time to cut the inside of a sidewall? We assume we hit an object in the roadway that we did not notice. Or maybe our low-pressure off-roading abused the casing, causing the eventual separation. Regardless, we went straight to our Les Schwab dealer and bought our second set of LT255/85R16 D-range tires. The tread remaining on our damaged left-front tire was pro-rated, and we received a credit for $50.39.
The End Is Not Near!
When we discovered our damaged sidewall and replaced our TXRs we had traveled 46,818-miles on our original set of 255s, all of which had 7/32 of tread depth remaining. We had used 11/32 of the original 18/32 of tread depth. We had averaged 1/32” of tread wear every 4,256 miles. At this rate of wear we could have driven 68,096-miles before reaching the minimum legal tread depth of 2/32! That is very impressive! As the saying goes, “your mileage may vary”.
I believe the Current TXRs are called TXR II, a slightly modified tread design. I really like the tread void ratio, and consider it quite similar to the Cooper ST.
Negatives:
The TXRs caused a side to side wiggle in the steering wheel that I didn't find too objectionable on the F350 but I didn't care for when I bought a third set for TXRs in 2005 for a Jeep LJ Rubicon. I had this third set siped 13/32” when new which in hindsight I think was too deep and caused tread squirm.
The sidewalls are softer (nice ride but...) maybe close to the Cooper ST/maybe not the most rugged design?
The second set on the F350-follow-up:
I was antelope hunting in the Nevada desert a few years ago with low PSI, about 20-25 in the front with a heavy diesel, driving it pretty fast/hard on dirt roads with some small rocks when I received a slow leak puncture at the edge of the tread in the sidewall from a very small but sharp stick/ piece of brush. After this I decided I needed a tougher tire for the F350. I later bought a set of Toyo M55s as you have read elsewhere. Less void, about the same noise/volume but a different tone. You know the rest of the story.
The second set on the F350 were also not going to last nearly as long, but I'm quite confident that was because I was not driving the truck as smoothly and slow as before.
I looked into buying another set (TXR II) a few months ago, but found availability an issue for me locally and decided against them. There are too many other good choices with local retailers.
