I got my first real workout yesterday with the loaded tires and the 2" wheel spacers. The stability with a loaded loder bucket is quite dramatic, and makes operations much faster, easier and safer. On the other hand, if you have any illusions that loading turf tires will increase traction, I would say that is a big NO. In fact, in really muddy conditions, I think it actually makes it WORSE. It's like trying to push a lawn roller out of a mud bog. My only loaded tire experience is with N-series Ford tractors, which when used with Ag tires, makes a HUGE traction difference, because the ags will dig down until they hit something solid enough to power you out. With the BX with turfs, once the tread fills with mud, it's pretty much game over. I thought it MIGHT help somewhat on dry ground, but that didn't really seem to be the case either. I'm still glad I did it, because the stability will help a LOT on my hilly ground, and make bucket operations better, but I guess I was hoping for a little too much on the traction. I would like to hear from BX guys with loaded R4s and R1s and see what their experience has been.
