I bought a bobcat 825 last fall. I haven't had a whole lot of time to use it yet. It has very bald tires on it right now, but for what I have been using it for (work around the farm) it has been nice because it doesn't tear up the grass much. Unfortuantly I may have some emergency work to do with it (flooding issues) and I plan on building a clay dike with it this spring/summer. I know that I will be working a lot more in the mud and muck at that point of time. The slicks aren't so cool for that. I am sure new tires will make a world of difference in the sloppy stuff. I am concerned that I will regret having them durring the 90% of the time that I don't have any traction issues. My thought is that maybe I should buy a new set of rims with my new set of tires and then be able to swap rims/tires depending on what my current project is. What do you guys think, am I over estimating the value of my slicks? Should I spend the extra $500 and get rims with the new tires or is it just a waste of time. I don't have a lot of experience here, so I am operating on theory, and would really appretiate some advice from the experience of the group. FWIW, it runs on 12.5x16 tires. thanks, Mr_C
