I thought about using a pallet jack, just wasn't sure how I would keep the tire from tipping. Maybe I'll make a custom short pallet that I can slide onto the jack first that has a vertical frame that I can strap the tire to such that the tire will sit directly on the pallet jack and this custom pallet will be between the jack and the tire. This may be my best option since I know I can borrow a pallet jack from work for the weekend when I'm ready.
the best of this idea I got from a man with a one man shop at his house, he took a pallet jack, shortened it to about 30" long, welded an upright guard to it to strap the tire to so it couldn't fall. Then he welded two rollers running long ways on the forks so if things moved he could rotate the tire to line up the studs. I need to go up there and get a picture, I will have one for myself! I've seen him work with loaded 38's with no problem
I think it would be cheaper to have your dealer or a farm field service outfit do the change for you.
I need to remove the loaded rear tires to install wheel spacers. They weigh 700-800 lbs each. Anyone here had to remove loaded tires and how did you do it while minimizing the risk of the tire falling over and not being able to stand it back up?
