Last year, for the first time in the 17+ years of ownership of my BX22, I installed chains, since they were predicting a horrific Nor'easter. I pulled out of the garage, and within 10 feet, I realized that they were too bumpy for me. I took them off and hung them back on the wall where they hung for decades. I never needed chains before, and I doubt that I will ever need chains. I use turf tires, and they are loaded, along with a 600# weight box in the rear. I snowblow first, and after the bulk of the snow is gone, I go over the driveway with the plow. Swapping implements is easy, and this year, with the BX23S, it should be even easier.
The only reason that I can see having to use chains, is if I had a steep hill to climb. If that were the case, I would use my F250 plow truck that was retired when I got the BX.
