Dave, this is a different train of thought but if you are simply trying to get away from the deep lugs of your current tires, why not simply replace the tires with regular treadIJ I was surprized recently to learn how close the footprint of a 24.5-32 is to a 30.5-32. Firestone lists them at 430 and 450 square inches, flat plat, respectively. I found this out when I was wondering if my new grain buggy had large enough tires. Just a thought. Ed.
