I've got a Speeco 22 ton splitter, and, its been a great little splitter. But, for one thing, i'd like to upgrade to a taller tire/wheel combination. Its a pretty small tire/wheel, and i haven't measured it, any idea's on what might work? The original tire/wheel is held on by a large nut , there are no lug nuts on it. Any idea's for a good tire / wheel size for this change over.
