Yeah just had to do this a few weeks ago… bought the Harbor Freight tire changer (but didn’t know about the additional attachment at the time), and removing the old tire was a big ordeal… then installing the new tires wasn’t so bad, but it took me forever to seat the bead. 1st problem was getting the bead to get close enough to the step so air could stay. It took some fidgeting with the ratchet strap to get it going. 2nd problem was getting the bead to seat…. I was just too fearful of overpressuring it but I had to hit like 35-40 psi before it made the loud “pop”; staying around 25 psi did nothing. But after having done it, I did have the same sentiment of “hey, at least I know how to do it, but I don’t want to do it again anytime soon!!”
