I have had foam filled tires in front loaders in a scrap yard and in UTVs. It is great for never flat in that environment. It adds a lot of weight and a lot of work ($$$) when they eventually have to be changed due to wear. It is also difficult to get them to balance, but that didnt matter in my low speed environment. When it came time for new loader and UTV I did not foam fill the tires. I decided it wasnt worth the cost.
