have run them for years. we are in deep south texas with thorns, staubs, etc. I use slime too.
several thoughts. There are three sizes - 25, 26, and 27's. The 25 and 27's are more aggressive tread - little rougher riding but much more rubber and tread on them. The 26's are not as thick or aggressive tread but smoother riding. If you are using for hunting mainly then the 25 or 27 are the choice. Only difference in those two are that the 27's are an inch higher clearance. I prefer the 27's.
Overall they have saved us lots of headaches -
x2. Like TLK said, there are 3 different sizes with the 25s and 27s being the more aggressive. They are extremely rough due to the thick sidewalls, but we aired them down to around 10 psi and they are much more manageable.
We have had our set of the 25" on 2 different Kubota RTV's and they've held up to everything we've put them through. Cactus, mesquites, rocks, sand...you name it and I put it through it. (just don't tell pops
) Only got it stuck once, and that was due to high centering it, not the tires fault.
