FWIW, my tractor's manual says that the warranty will be voided if you put foam in the tires.
Honestly, I don't know what my tractor's manual says about it... I don't have one. However, my 70A loader manual recommends it. That could be an interesting situation if the two contradict each other. That's moot in my case as I am my own warranty station for my tractor.
