This may seem ridiculous, but I am looking for old skid steer tires that have worn down smooth but are not dry rotted. They are used on my 843 bobcat on the 15 x 15.5 rims that i use while working on grass to avoid damage. My old tires are just too dry rotted to use anymore, and they are coming apart as well as losing air. If I get a new set they are so aggressive that I leave tracks everywhere. Tire places throw them out and I have found them in the dump from time to time. Is there anyone out there with any more ideas where to look.
