I have put new tires on the rear of three of my tractors over the years, and have had to fix a few more too. I always take the rim/ tire off and do them flat on the ground like you would with a smaller tire or truck tires. (I have changed my share of them too.) My neighbor would change them while still on the tractor and I have heard that is how most tire men do it. I have never seen it done that way myself. Just got wondering how most folks here do them / have them done. Main issue for me is breaking stubborn beads loose, I know that there is tools that would work with the rear wheel on the tractor but I don’t have any. Thank you for any replies in advance.
