I would imagine most tractor tires will rot off before they would ever be half wore out and far more likely to get changed because they get cut or damaged. I've really been tempted to just get industrials, but the chains work real good- perhaps even better? Like you say... down the road maybe.... On the bright side for me, the turf tires are a little bit bigger profile than the industrials. I never understood why that is that there is a different size spec between the two types of tires? (Three actually)
