Ordered a set of mounted bar tires for snow removal and plan to add www fluid as ballast, consulted the OM table for liquid ballast. It warns not to use the factory wheel weights and liquid together as this "may damage transmission" Certainly this combination weighs less than wheel weights and the available rear ballast box. Absolutely weighs less than wheel weights and a backhoe. Have a steep drive to plow and the mindset that "more is better" when it comes to weight. What am I missing ?
