My tires are a bit worn from all of the spinning they have been doing most of this year on wet clay, that is in turn sitting on top of large rocks. And then dragging a 720# box blade or digging out tree stumps with the grapple bucket. But my tires are in better shape than yours.
For what I am doing, if I were having traction problems attributed to tire wear, I would probably add chains to the rear as I am not doing any kind of finish work on the property I am clearing for our next home site. Plus my rears are already loaded to ~450# each and operating weight varies from 6900# - 7200#, which is more than yours but the same concept.
Chains on yours may cause erosion or at a minimum tear up the grass, which can also cause erosion.
My rears were filled with windshield washer fluid (methanol) by the dealer and I have no idea of the concentration.
