I can see that being useful in many ways. How about a tractor pull or race for more grip? Also could be less heat and less blowouts on the drag strip.maybe?
The added weight of the water gives better traction for everyday use and makes it more stable for front end loader use. I would never fill the tires with water for high speed use because it will throw them out of balance.
Been running water in the tires for over 18 years in this one with no rim problems. I know where a 4010 is that has been using water in the tires since for over 30 years without issues.
