Hello, Rob,
I am glad to read that your knee situation is progressing well.
About the Yoko tires? I wish I could give you an in-depth reply, but I cannot authoritatively compare the Yokos to another brand of big tire.
The Yokos (33 x 12.5) were on my current CJ (Yes, I have loved others.) at purchase, some 16 months ago. The Jeep also came with a "spring pack" lift to accommodate the Yokos.
About all I can offer is that the Yokos perform well on the street. They are very quiet, and they perform well on the wet and dry roads typical of our spring and summer. They also perform well on the snowy/icy roads typical of an upstate New York winter.
By way of my location, the nearest large city is Syracuse. I also keep a boat at a marina near Darrin's @ ECOR shop. (One of these days, I will go to ECOR and say, "hello.") I mention my location because the long-term average annual snowfall here is approximately 115 inches. Consequently, a good all-around compromise tire is almost mandatory for all vehicles, to include my street Jeep. I can only advise that I am satisfied with the Yokos given the road conditions in which I must drive.
As regards off-road performance of the Yokos -- I have no clue. I have never driven this Jeep off road -- unless driving on my back lawn would qualify. Having been born only a short time after the earth cooled, age and medical restrictions have caught up with me and limit what I should attempt in my Jeep.
I regret not having gotten into the Jeep thing some forty years or so ago. How I would love to take a Jeep into the woods like you, Tug and so many of our fellow Jeepers.
I know the above won't help much by way of answering your tire questions, but that is about all I can honestly offer as regards the Yokos.
BTW -- I did read your post about the Paragon excursion of 2004 and noticed that there are "bunny" trails. Who knows? Maybe I will be able to show up, meet some fellow Jeep crazies, give those Yokos a work-out and the street-queen a mud bath.
If my Jeep could smile, I bet she would -- and so would I.
Regards,
Inspector-G
