There is lots of controversy with this question. I have R-3's on my 4410 and am very happy with them. I have more than enough traction for most of my work. From pushing snow with the fel, snowblowing, heavy digging in dirt and gravel, mowing lawn and even cleaning wet soupy corrals. Farmers like the fact that if I run into something cleaning corrals at least I don't destroy it like a larger tractor does.
We have fairly sandy soil in this area which no doubt helps my situation. If we had sticky gumbo I could be looking for different tires.
The only issue I've had is that I've needed to replace several sets of front tires because of sidewall cuts. I now have a set of 10 ply tires on the front and we will see how they do.
